Q.1 What is Server Farm ? Ans:- Server farms are groups of servers running MetaFrame Presentation Server that you can manage as a unit, enabling you to configure features and settings for the entire farm rather than configuring each server individually.Servers in a farm share a network connection and a single data store of the farm’s configuration information. Q.2 What is Independent Management Architecture (IMA) ? Ans :-Independent Management Architecture (IMA) provides the framework for server communications and is the management foundation for MetaFrame Presentation Server. IMA is a centralized management service comprised of a collection of core subsystems that define and control the execution of products in a server farm. IMA enables servers to be arbitrarily grouped into server farms that do not depend on the physical locations of the servers or whether the servers are on different network subnets. IMA runs on all servers in the farm. IMA subsystems communicate through messages passed by the IMA Service through default TCP ports 2512 and 2513. The IMA Service starts automatically when a server is started. The IMA Service can be manually started or stopped through the operating system Services utility. Q.3 What Independent Computing Architecture (ICA) ? Ans:- The Independent Computing Architecture (ICA) is the communication protocol by which servers and client devices exchange data in a server environment. ICA is optimized to enhance the delivery and performance of this exchange, even on lowbandwidth connections. Q4. What Information is stored in Data store ? Ans:-Persistent farm-wide information (information about published application configurations, available servers, authorized Citrix administrators, trust relationships, and the licenses available) is stored in a data store on the data collector. Although a database of some kind (Oracle, Microsoft SQL Server, MS Access, or IBM DB2, MSDE ( MSDE in no more supported by PS4.5) • Farm configuration information • Published application configurations • Server configurations • MetaFrame administrator accounts • Printer configurations • Trust relationships Q5. How many server can I have in a Zone ? Ans:- By default, a single zone supports 512 member servers (prior to MetaFrame XP Feature Release 3, the default was 256 member servers). If a zone has more than 512 member servers, each zone data collector and potential zone data collector must have a new registry setting. This new setting controls how many open connections to member servers a data collector can have at one time. You can configure this value by adding the following value, expressed in hexadecimal notation, to the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA\Runtime\MaxHostAddress CacheEntries (DWORD) Value: 0x200 (default 512 entries)

Note If you do not have more than 512 servers in a zone, increasing this value does not increase the performance of a zone Q6. What is LHC and where stored ? Ans:- The local host cache (LHC) is an Access database located on each member server in %ProgramFiles%\Citrix\Independent Management Architecture. The local host cache is important as the backup in case the member server temporarily loses access to the data store, but it is also helpful under normal conditions—the member server can read or write information in its local host cache instead of accessing the data store every time it needs something. The cache is populated when the IMA service on the member server starts, then by periodically (normally, at intervals of 10 minutes; you can edit this setting to improve performance) Q7. What is Data Collector server ? Ans:-Zone data collectors are communication gateways between zones in farms that have more than one zone. Zone data collectors communicate information used by MetaFrame Presentation Server to list available applications for users and, when users open an application, to locate the most appropriate server on which to run the application. The server responsible for gathering information about the server farm and making this information available to all member servers is called the data collector. The data collector gets its information from the member servers in its zone. Any time any of the following events (collectively known as session data) takes place, the member server informs its data collector:

• ICA client logons and logoffs • ICA session disconnects and reconnects • Server and application load changes • License acquisition and release • Server brought online or goes offline (either reboots or restarts the IMA service) • Published application changes • IP and media access control (MAC—the hardwired network card address) address

changes

Using this information, the data collector can provide a clear picture of the MetaFrame servers in the farm at any given time: the servers available, the clients using those servers, the load on each server, the licenses in use, the applications available in the farm, and the network address of each server. For faster access, the data collector keeps all session data in RAM. If the data collector doesn’t hear from a member server within the preset interval (by default, 60 seconds), the data collector will ping the member server through IMA to make sure that the server is still online. Q8. How can I verify Win2K Terminal Services is In Application Server Mode Ans:- Again, MetaFrame only works on Win2K servers with Terminal Services installed in Application Server mode, not Remote Administration mode. You can easily check the mode from the Terminal Services Configuration window, located in the Administrative Tools

program group. Your view of the terminal server mode should look like this figure. Q9.What is IMA Service Port ? Ans :- 2512 Q10. Can I change IMA service port ? Ans:- Yes, Normally, using the default port (2512) for the IMA service will work without any problems. On the off chance that you need to use another port, you’ll need to edit the server’s registry

Be careful when editing this key’s value! By default, it’s presented in hexadecimal format. If you type the value in decimal, you need to select the option button in the Edit DWORD Value dialog box that changes the value from hex to decimal. Note :- If no other servers were in the farm when you changed the IMA service’s port, you’re home free—when installing the other servers, just be sure to point to the correct port when you

�� ! ��"�� #��

reach the stage of the wizard that Figure 4.12 shows. If you’d created other servers in the farm before changing the port, you’ll need to edit the value of PsServerPort key (also located in HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA subkey) to the correct port number. Q11. How Client connects to Presentation Server via web ? Ans:- A user accesses the Web Interface URL with the Web browser over port 80, similar to any other Web site.

1. The IIS-based Web service where the Web Interface resides has a default page to redirect the user automatically to an HTTPS/SSL URL that then passes through the Secure Gateway service on the same server to secure the traffic over port 443.

2. The user is now interacting securely with the Web Interface/Secure Gateway environment and is presented with the login page.

3. The user enters his credentials and submits the authentication request, which is passed encrypted over SSL to the Secure Gateway service (thus preventing the user credentials from being passed in plain text).

4. Once the Secure Gateway service obtains the user credentials, it opens a state ticket with the STA server and then passes the credentials to the MetaFrame farm over the defined XML service port. The default is port 80.

5. The user credentials are checked via the Citrix XML service and verified by Microsoft Active Directory or other directory services such as Novell e-Dir.

6. Based on a successful authentication, the XML service communicates back to the Web Interface service and dynamically renders an access page for the user with the appropriate applications. If any problems occur, they're displayed on this page within the MetaFrame Message Center.

7. When a user clicks an ICA-published application, the Web Interface service sends the IP address and port for the requested MetaFrame server to the Secure Ticketing Authority Server (STA) and requests a session ticket for the user. The user-installed ICA client then securely establishes an ICA connection over SSL using port 443.

8. The Secure Gateway service receives the session ticket over port 443 from the client and contacts the STA for ticket validation. If the ticket is valid, the STA returns the IP address of the MetaFrame server on which the requested application resides. If the session ticket is invalid or has expired, the STA informs the Secure Gateway service and an error message appears on the client device.

9. On receipt of the IP address for the MetaFrame server, the Secure Gateway server establishes an ICA connection to the MetaFrame server over port 1494 in a proxy-like manner. When the ICA connection is established, the Secure Gateway server encrypts and decrypts the data flowing through the connection.

Q12. What are terminal service mode ? Ans :- There are two modes remote Administration Mode & Application Mode Q13. What is Zone ? Ans:- A zone is a grouping of servers that share a common zone data collector. A zone data collector is a server that manages dynamic information about the servers in the zone. Each farm has at least one zone. Q14. What are the Zone Data Collector preference levels ? Ans:- Most Preferred Preferred

Default Preference Not Preferred Q15. What Data base can I use for data store ? Ans:- Microsoft Access. Access is a lightweight database that is included with Windows server operating systems. The Access database is created on the first server in a new farm. It is most appropriate for small to mid-sized farms. Microsoft SQL Server 2000 Desktop Engine (MSDE). MSDE is a database engine based on Microsoft SQL Server core technology. The MSDE database is created on the first server in a new farm. It is most appropriate for small to medium-sized farms and can be administered using standard Microsoft SQL Server tools. Microsoft SQL Server. SQL Server is a true client/server database that offers robust and scalable support for multiple-server data access. It is suited for use in farms of any size. Oracle. Oracle is a true client/server database that offers robust and scalable support for multiple-server data access. It is suited for use in farms of any size. IBM DB2. DB2 is a true client/server database that offers robust and scalable support for multiple-server data access. It is suited for use in farms of any size. Note :- MSDE is not more supported by Citrix PS 4.5. (It is replaced by MS SQL Express Edition 2005) Tested databases • Microsoft Access Jet Engine 4.0, Service Pack 1 through Service Pack 8 • Microsoft SQL Server Desktop Engine (MSDE) 8.00.760 for Windows 2000, Service Pack 3 or later • Microsoft SQL Server 7.0 with Service Pack 2 • Microsoft SQL Server 2000 • Oracle Server 7 (7.3.4) for NT • Oracle Server 8 (8.0.6) for NT • Oracle Server 8i (8.1.5, 8.1.6, 8.1.7) for NT and UNIX • Oracle Server 9i (9.0.1) for NT • Oracle 9i R2 for NT and Solaris • IBM DB2 Version 7.2 with FixPak 5-13 • IBM DB2 Version 8.1 with FixPak 1-7a Q16. What type of Data base connectivity used by Citrix ? Ans:- MetaFrame Presentation Server will connect directly to it or indirectly through another server. Direct access. To make a direct connection to the data store, a server must have the appropriate ODBC drivers installed and configured properly. The server then connects directly to the server on which the database is running. Indirect access. For indirect access, a server connects to an intermediary server running MetaFrame Presentation Server that connects to the data store directly. Note Although it is possible to configure multiple servers in the farm to connect directly to a single MSDE database, Citrix does not recommend this configuration because it is not supported by MSDE. MSDE allows only five connections per installed instance of MSDE. If more than five servers attempt to access the MSDE database at the same time, they cannot connect. Q17. What are Citrix Editions ? Standard Edition – Presentation Server, Metaframe Administrator, Printer and Policies

Preference and Failover. 5. Enable Zone Preference and Failover and assign a connection order to each zone. Q23. What is Local Host Cache Synchronization and recreation A subset of data store information, the local host cache, exists on each server in the farm, providing each member server with quick access to data store information. The local host cache also provides redundancy of the data store information, if for example, a server in the farm loses connectivity to the data store. When a change is made to the farm’s data store, a notification to update the local host cache is sent to all the servers in the farm. However, it is possible that some servers will miss an update because of network problems. Member servers periodically query the data store to determine if changes were made since the server’s local host cache was last updated. If changes were made, the server requests the changed information. You can adjust the interval by which member servers query the farm’s data store for missed changes. The default interval is 30 minutes. You can configure the interval using the following registry key on each server you want to adjust, with the value expressed in hexadecimal notation: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA\ DCNChangePollingInterval (DWORD) Value: 0x1B7740 (default 1,800,000 milliseconds) You must restart the IMA Service for this setting to take effect. To recreate the local host cache, stop the IMA Service and then run the command dsmaint recreatelhc. Running this command performs three actions: You must restart the IMA Service after running dsmaint recreatelhc. When the IMA Service starts, the local host cache is populated with fresh data from the data Store Q24 What are Citrix Metaframe administrator permission levels ? ��Full access to all areas of server farm management View-only access to all areas of server farm management Mixed levels of access to areas of farm management or specific tasks within those areas; administrators can have a mixture of view-only access, write access, or no access Q25. What to do when IMA Service Fails to Start ? ��The following guidelines and recommendations can be useful when the IMA Service fails to start: • Examine the following registry setting: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA\ Runtime\CurrentlyLoadingPlugin • If the value is blank, the IMA Service could not connect to the data store or the local host cache is missing or corrupted. • If a value exists, the IMA Service made a connection to the data store. The value displayed is the name of the subsystem that failed to load. • If you are connecting directly to the data store, verify that ODBC connectivity exists. • If you are connecting to the data store through an intermediary server, verify that the IMA Service is running on the server that is connecting directly to the data store.

• Review the entries in the event log for the IMA Service error code that is returned. Master page: First • Verify that the Spooler service is started in the System context rather than for a user. • If you see an “IMA Service Failed” message (with error code 2147483649) when restarting a server, the local system account may be missing a \temp directory. Change the IMA Service startup account to the local administrator. If the IMA Service starts under the local administrator’s account, check for a missing temp directory. Switch the service back to the local system account and try manually creating the temp directory %SystemRoot%\temp. Verify that both the TMP and TEMP environment variables point to this directory. For more information, see Microsoft Knowledge Base article 251254. • The Service Control Manager has a time-out of six minutes, but the IMA Service can take longer than six minutes to start when the load on the data store database exceeds the capabilities of the database hardware or when the network is experiencing high latency. If the Service Control Manager reports that the IMA Service could not be started but the service eventually starts, ignore this message and change the default time-out value. Q26. How to set IMA Service Logging ? �� To enable server logging of IMA events 1. Modify the following registry values in HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA\Tracer: • Name: Log to Debugger Type: REG_DWORD Data: 0x0 (disables debug output) or 0x1 (enables debug output) • Name: Log to File Type: REG_DWORD Data: 0x0 (disables file output) or 0x1 (enables file output) • Name: LogFileName Type: REG_SZ Data: full path and file name of the output file 2. The HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA\Tracer registry key contains a subkey for each subsystem about which information can be traced. Tracing for all subsystems is on by default, but the specific types of messages for the subsystems are off. To enable tracing for a subsystem, both the default value (specified as the first value in the key) and the message values must have a value of 1. The default value must be 1 and must not be changed. Other values within each key correspond to types of messages to log and are set to 0 by default. To enable tracing for those items, set their value to 1. Q 27. What is ICA Sessions ? ��An ICA session is the communications link between clients and servers that users establish to run applications. In an ICA session, a server transmits an application’s screen display to the client and the client sends the user’s keystrokes, mouse actions, and local data to the application running on the server. The default port on servers for ICA sessions is 1494. This port must be open on firewalls for inbound communication if clients are outside the firewall. The outbound port used on the client for the ICA session is configured dynamically when the session is established. Q28. What is Citrix XML Service ? ��Citrix XML Service is a component of MetaFrame Presentation Server. The service

��

� ��

�� ! ��"�� #��

is installed by default on all servers. When clients are configured to use TCP/IP+HTTP for ICA browsing, the XML Service communicates published application information to clients using the HTTP protocol and XML data. The XML Service also communicates published application information to servers running the Web Interface For example, when a user launches a published application in Program Neighborhood, the client sends a request for the application. The XML Service responds with the address of a server on which the application is published. With the Web Interface, for example, a user connects to a Web page using a Web browser. The XML Service provides a list of available applications to the server running the Web Interface. The Web server displays the available applications on the user’s personalized application Web page. What is port 1604? If TCP/IP is specified as the server location network protocol and (Auto-Locate) appears in the Address List box, clients send UDP broadcasts to the ICA browser service on port 1604 to locate servers and published applications. Q29. ICA Browsing ��ICA browsing is a process in which a client transmits data to locate servers on the network and get information about the server farm’s published applications. ICA browsing occurs when: • Users launch published applications. The client sends a request to locate the application on a server. If you are using Load Manager, a component of MetaFrame Presentation Server for Windows, Advanced Edition and Enterprise Edition, the client gets the address of the server with the lightest load. • Program Neighborhood users display the Application Set list in the Find New Application Set wizard. Q 30. What are Components of MetaFrame Presentation Server ? �� Management Console for MetaFrame Presentation Server. Enables complete, singlepoint management of the entire server farm through a comprehensive interface. Installation Manager. (Enterprise Edition only.) Provides centralized, farm-wide installation capabilities such as support for unattended installs, packager rollback, scheduled package delivery, and MSI support. Installer Service. (A component of Installation Manager.) Provides the ability to install applications packed by the Packager to computers running MetaFrame Presentation Server. Packager. (A component of Installation Manager.) Monitors application installation routines and packages all application files for distribution to your server farm. Resource Manager. (Enterprise Edition only.) Provides customizable metrics and reporting, real-time graphs and alerts, and capacity planning for server farm resources. Load Manager. (Advanced and Enterprise Editions.) Provides load balancing of user connections across servers to more effectively utilize server resources. Network Manager. (Enterprise Edition only.) Provides the ability to administer server farms through the native management consoles of leading network management solutions. Program Neighborhood/Program Neighborhood Agent.

What are Citrix Client Deployment Methods ? �� • Using Microsoft Systems Management Server (SMS) or Active Directory Services in Windows (for clients that can be installed with Windows Installer packages) • Using the Components CD • Using a Web browser • Downloading from a network share point • Using installation floppy disks Q32. Anonymous Users ? ��During MetaFrame Presentation Server installation, Setup creates a special user group named Anonymous. By default, this user group contains 15 user accounts with account names in the form Anonx, where x is a three-digit number from 000 to 014. By default, anonymous users have guest permissions. When a user starts an application that is configured for anonymous users, the server does not require an explicit user name and password to log the user on to the server and run the application. Anonymous users are granted minimal ICA session permissions that include the following properties that differ from standard ICA session permissions for the default user: • Ten-minute idle (no user activity) time-out • Log off from broken or timed out connections • No password is required • The user cannot change the password When an anonymous user session ends, no user information is retained. The server does not maintain desktop settings, user-specific files, or other resources created or configured for the client. Q33. Explicit Users ? ��An explicit user is any user who is not a member of the Anonymous group. Explicit users have user accounts that you create, configure, and maintain with standard user account management tools. Explicit users who log on to a server farm to run applications have a persistent existence: their desktop settings, security settings, and other information is retained between client sessions in a specific user profile. Q34. What is isolation and Isolating Published Applications ? ��Isolation environments enable you to isolate a published application within a virtual environment. The isolation environment protects the operating system and applications from conflicts and other complications that frequently occur between incompatible or legacy applications. The isolation environment creates an environment or user-specific copy of the system resources modified by the published application during installation or runtime. This allows the application to function without affecting the rest of the system. The isolation environment also provides a virtual mapping from an application to operating system resources.

��

� �

� �

� ��

�� ! ��"�� #��

The mapping is accomplished through the use of rules that specify how an application behaves within an isolation environment. The basic steps for isolating an application are as follows: 1. Through testing, identify applications that malfunction when used through MetaFrame Presentation Server or Terminal Services. 2. Ensure isolation environments are enabled for the farm. (By default isolation environments are enabled at the farm level.) 3. Create isolation environments. 4. Configure the properties of the isolation environment. 5. Isolate the published application. Q35. How to Configure an Isolation Environment ? ��The default settings of an isolation are designed to resolve most compatibility issues; however, you can refine and optimize isolation environment settings as required.When you opt to configure an isolation environment, you decide the following characteristics: Applications. Specifies applications installed into the isolation environment as well as applications that are candidates for publishing. You can also specify other applications published on the server farm that are associated with this isolation environment. Roots. Specifies the virtual directories and registry locations in which files modified by users (user profile root) and applications (installation root) reside. You can set root locations for the following: • Farm level. You can configure root locations only at the farm level • Server level. Root locations set at the farm level apply only to enabled servers Rules. Specifies whether or not isolation, redirection, or ignore rules need to be applied to system resources, such as files, registry, and named objects. Security. Specifies the type of security policy, such as enhanced or relaxed, to apply to this isolation environment. Selecting enhanced security prevents execution of files located in the user profile root. To configure the properties of an isolation environment 1. In the left pane of the console, select Isolation Environments. 2. In the Contents tab, select the isolation environment to configure. 3. On the Actions menu, click Properties. 4. Use the Properties page to add applications and configure roots, rules, and security settings for the isolation environment. For specific information about each Properties page, click Help. 5. To save your settings, click OK. Q36.Can I Uninstall an Isolated application from Add remove program ? ��Unlike removing applications not installed into an isolation environment, you can not reliably use Windows Add/Remove Programs to uninstall applications installed into an isolation environment. Windows Add/Remove Programs may not completely delete everything that was installed, resulting in an incomplete uninstall. Note Citrix recommends before deleting an isolation environment to follow your company policy for backing up user-specific files.

�� $� ��

� �

� �

� ��

�� ! ��"�� #��

To uninstall all applications installed into an isolation environment 1. Delete all the files that reside in the installation root location of the isolation environment (typically C:\Program Files\Citrix\AIE\<aiename>) 2. Use regedit to delete the registry entries under installation root (typically HKLM\Software\Citrix\AIE\<aiename>). 3. Because the server does not automatically update published application links, after you remove applications from a deleted isolation environment, use the console to delete the published links for the uninstalled applications. Because an application file system and registry are isolated, this procedure provides a clean uninstall of the applications from the server. Q 37 What Session Information Displayed in the Console ? ��The session information that appears in the console includes details that help you identify the various types of sessions and the users associated with the sessions. The following column labels appear on tabs that display session information. User. The name of the user account that initiates a session appears in the User column for each session. In the case of anonymous connections, the user name is a string with the letters “Anon” followed by a session number. Server. The servers on which the selected application is running appear in this column. Session. The Session column identifies a session with a name that includes the protocol that the session uses, usually ICA or RDP (Remote Desktop Protocol). The name also includes the network protocol for the session, and a number that distinguishes the session from other sessions that are running on the server. Session ID. The Session ID is a unique number that begins with 0 for the first connection to the console. Listener sessions are numbered from 65,537 and numbered backward in sequence. State. A session’s state is listed as Active, Listen, Idle, Disconnected, or Down. The meaning of session state labels is explained in the following section, which describes commands you use for managing sessions on servers. Type. The type of connection being used to connect to the server, ICA or RDP, for example. Client name. This column displays the name of the client device that is running the session. Application. The name of the published application running within this session. Logon Time. The time at which the user logged on. Idle Time. The amount of time during which the user has not interacted with the Application Q38. How Automatic Client Reconnection Works ��When a client detects an unintended disconnection of an ICA session, it attempts to reconnect the user to the session until there is a successful reconnection or the user cancels the reconnection attempts. When a connection breaks, it may leave the server session in an active state. Users can reconnect only to sessions that are in a disconnected, or inactive, state. Cookies containing keys to user credentials and session IDs are created on the client device when ICA sessions are started. Because users can be reconnected only to disconnected sessions, Auto Client Reconnect uses the cookie on the client device to disconnect an active session before attempting to reconnect. Sometimes automatic

��

� �

� �

� ��

�� ! ��"�� #��

reconnection can result in a new ICA session instead of a reconnected session. A new session can be created if: • The cookie on the client containing the key to the session ID and credentials expires. When the session starts originally, this cookie is sent to the client. This cookie persists on the client for several minutes after a connection breaks. • The cookie containing the key does not force users to reauthenticate. Instead, users are prompted with a logon screen before reconnection occurs. The following types of disconnections do not result in automatic reconnection attempts: • Users disconnect ICA sessions by exiting applications without logging off. Clients do not make automatic reconnection attempts in this case. • Anonymous users’ sessions are disconnected. Q 39. How to apply a Policy ? ��By default, newly created policies are not applied to any sessions. Before a policy has an effect, you must create a filter for it so the server can apply it to matching sessions. You can filter sessions and apply a policy to them based on a combination of the following criteria: • Access control through which a client is connecting to a session • IP address of a client device connecting to a session • Name of a client device connecting to a session • Users or user groups associated with a session • Server hosting a session Q 40 What are MetaFrame Presentation Server Commands ��

Setting a Static Citrix Vendor Daemon Port Number

�� %� ��

�� ! ��"�� #��

To set the port number, add the path for the options file and the parameters for the new port number including the startup license file. The modified syntax in the license file is as follows: VENDOR CITRIX options="C:\Program Files\Citrix\Licensing\MyFiles\CITRIX.opt" port=number When setting the Citrix vendor daemon port number, you must specify the path to the citrix.opt file and the port number in every license file on the license server and all subsequent license files that you download. To set a static port number for the Citrix vendor daemon

1. From the Windows Services panel, stop the Citrix License Management Console service. 2. Open a license file with any text editor (by default, the license files are located in

C:\Program Files\Citrix\Licensing\MyFiles). 3. In the license file, locate the line VENDOR CITRIX. 4. Modify the line by appending the following: options=<path to the options file> port=<port

number> Example: VENDOR CITRIX options="C:\Program Files\Citrix\Licensing\MyFiles\CITRIX.opt" port=27950

5. Save the license file with a .lic extension. 6. Repeat Steps 2 through 5 for each license file on the license server. 7. From the Windows Services panel, restart the Citrix License Management Console

service and the CitrixLicensing service to make your Citrix vendor daemon port number changes take effect. If a TCP/IP

port number is specified on the VENDOR line, the Citrix vendor daemon may not restart until all the clients close their connections to the vendor daemon. Note: Do not restart the services until all license files on the license server have the same port number. If the Citrix vendor daemon encounters different port numbers in the license files, the license server stops running.

8. Verify that the new Citrix vendor daemon port number is being used by looking for the lines that use the new port number in the debug log (By default, this file is in C:\Program Files\Citrix\Licensing\LS). The lines will be similar to the following:

3:13:48 (lmgrd) Starting vendor daemon at port 27950 3:13:51 (lmgrd) Using vendor daemon port 27950 specified in license file Note: The text shown above many vary slightly depending on which version of Citrix Licensing you are running. Changing the License Manager Daemon Port Number If you need to change the port number, you must specify the new number in all license files on the server and in the firewall (if you have one). By default, no port number is listed in the license file. When the License Manager daemon does not find a port number listed in the license file, it uses port 27000. To change the license manager daemon port number

1. From the Windows Services panel, stop the Citrix License Management Console service.

2. Using a text editor, modify the SERVER line of the license file by adding a port number after the hostname. (by default, the license files are located in C:\Program Files\Citrix\Licensing\MyFiles).

For example: SERVER this_host HOSTNAME=mps_server1 27900 —or— SERVER this_host ANY 27900

service and the CitrixLicensing service to make your Citrix license manager daemon port number changes take effect.

Note: Do not restart the services until all license files on the license server have the same port number. If the License Manager daemon encounters different port numbers in the license files, the license server stops running.

6. Verify that the new Citrix license manager daemon port number is being used by looking for the line that uses the new port number in the debug log. The line will be similar to the following:

3:13:48 (lmgrd) lmgrd tcp-port 27900 Note: The text shown above many vary slightly depending on which version of Citrix Licensing you are running. Resource Manager Summary Database Data Source Name Q: Is the Resource Manager summary database Data Source Name (DSN) case sensitive? A: The RMSummaRyDataBASE DSN is not case sensitive. Q: Resource Manager was installed on two servers in my farm. After uninstalling Resource Manager from one of the servers, why does the Resource Manager icon remain in the Presentation Server Console even though the uninstallation completed without errors? A: When at least one member server in a farm has Resource Manager installed, the Resource Manager node appears in the Presentation Server Console when viewed on any server in the farm. Note The Resource Manager node can be removed from a Presentation Server Console by removing or renaming the ResourceManager.jar file found in \Program Files\Citrix\Administration\Plugins\ and restarting the Presentation Server Console. Q: I installed Resource Manager with the default metrics configured on a server and I receive alerts about high context switches. The server seems to be functioning correctly and none of my users are complaining. Is this alert serious? A: The default metric threshold values are a baseline configuration for an administrator to tune and they are determined for a minimal server configuration. Although most metric defaults are suitable as a “one size fits all” solution like Processor - %Processor Time defaults, some metrics like System – Context Switches / Sec must be tuned for the environment in which they operate. Q: What does the Zone Elections counter monitor in Resource Manager?

��

� �

� �

� ��

�� ! ��"�� #��

A: The Citrix MetaFrame – Zone Elections counter monitors the number of data collector elections that occurred in the server’s zone since the IMA Service started. Monitoring this metric can be useful to determine whether or not excessive data collector elections are taking place. Proactive monitoring can help prevent excessive amounts of data from transmitting between zones as elections are won. This can also be tracked with the Citrix MetaFrame – Zone Elections Won metric. Q: What needs to be done when I attempt to create the summary database and the procedure fails with this message appearing in the Resource Manager server log? A: This summary database message informs the user that there was an error deploying the schema for the summary database—for example, server log entry: 11 July 2002 12:26:02 - System - Failed to create summary database. The most common causes of this error are: There was a database problem while initially creating the summary database schema. For example, an Oracle database configuration such as the rollback segment is too small and non-autoextending; this can prevent successful deployment of the Resource Manager schema. Solution: Check the Oracle or SQL Server configuration settings to ensure there is enough space in the database to create the schema. Several megabytes should be enough space to create the schema. Also, check that all ‘rollback segments’ are ‘autoextending’; these can be tuned after the database is created. The database user has insufficient privileges to create the schema. For example, Resource Manager may not be able to insert data into tables or create packages. Solution: Ensure that the user has rights to the database and can successfully communicate with the database server. Cannot Launch Secure Applications through Internet Explorer If you have users connecting through a secure Web Interface page (HTTPS) and they receive an error message of “ICA file not found,” ensure the security settings within Internet Explorer are not set to Do not save encrypted pages to disk. To check security settings in Internet Explorer 1. Open Internet Explorer. 2. Click Tools > Internet Options. 3. Click the Advanced tab. 4. Scroll down to Security. 5. Be sure Do not save encrypted pages to disk is cleared. 6. Click OK. Content Redirection Options Are Disabled When Publishing an Application If you install and then publish applications after installing Presentation Server, you must update the file type associations in each server’s registry. To update file type associations in a server farm 1. Open the Presentation Server Console. 2. Expand the Servers node in the left window pane. 3. Right-click a server and select Update File Types from Registry. 4. When the file type updates are complete, check the properties of the published application. The content redirection options are now enabled. Isolation Environment Configuration When you install Office 97, 2000, XP, or 2003 into an isolation environment, fonts included with the Office suite are not available to the isolated Office applications. To access specific Office fonts 1. Create an “ignore” rule for the following registry keys where Office font

information is stored: • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\ • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Shared Tools\Font Mapping 2. Copy the Office fonts that you require from the installation root: %SYSTEMDRIVE%\Program Files\Citrix\AIE\AIE_Name\Device\Drive Letter\Windows\Fonts to the system font directory: %SYSTEMDRIVE%\Windows\Fonts 3. Using the procedures described in the Windows product documentation, install the required Office fonts. Installation Procedure To install Office into an isolation environment called My_AIE using the setup file setup.exe, type the following command: AIESETUP My_AIE file_path:\setup.exe Additional Installation Procedure—Office 2000 When installing Office 2000 on Windows Terminal Server, use a transform (.mst) file. The Microsoft Office 2000 Resource Kit provides a transform called Termsrvr.mst. Specify this transform using a command-line switch during setup. To install Office 2000 into an isolation environment on a Windows Terminal Server, append the TRANSFORMS parameter to the AIESETUP command: AIESETUP My_AIE file_path:\setup.exe TRANSFORMS=termsrvr.mst Registered Citrix Ports The following table contains the default registered Citrix ports.

Simplified Licensing for the MetaFrame Access Suite MetaFrame Presentation Server 3.0 uses a new method of licensing. Before you can use MetaFrame Presentation Server, you must install Citrix licensing, which includes a license server and a user interface for managing licenses known as the License Management Console. After you install Citrix licensing, download a license file from mycitrix.com and store it on the license server. Whenever you start MetaFrame Presentation Server, it contacts the license server to verify that you have a license for this product. The License Management Console lets you run reports to discover when licenses expire, configure the license server, and display license alerts. The console also provides a handy interface for downloading license files. You can also manage the license server by using command line tools and a configuration file known as the options file. Management of licensed products is simplified in the following ways: • All MetaFrame Access Suite products now use the same license management console • You centrally manage and monitor license usage • You can access your licensing data remotely • You can create reports allowing you to analyze trends in license usage • An electronic backup of all licenses is stored at Citrix • You can share licenses across farms

Enhanced Support for Large Farms Zone data collectors now monitor server load information for their own zone instead of the entire farm. This behavior reduces traffic among zones when users connect to applications, especially in large farms where zones are connected across high latency links

Zone Preference and Failover A new policy rule enables you to direct user connections to preferred zones and set transparent failover to backup zones when preferred servers are unavailable. When users open applications, the Zone Preference and Failover policy rule directs their connections to the server with the highest zone preference and lightest load

Extended Policies You can now create policies to apply connection settings based on server groups, IP addresses, and client names—in addition to users or user groups as in earlier releases. New policy rules give you broader control over bandwidth limits, zone connection preferences, audio options, and printing. You can use new policy rules to do such things as: • Direct user connections to a local zone and set failover options to other zones • Route print jobs directly from the server to the printer rather than through the client device • Control bandwidth limits for sessions • Control audio sound quality used by client devices The examples cited above include only a few of the new capabilities provided with connection policies. You can view other new and enhanced policy rules under the Policies node of the Presentation Server Console.

Enhanced Delegated Administration With Enhanced Delegated Administration, you can delegate areas of MetaFrame Presentation Server administration and farm management. Administrators can assign specialized staff members to perform specific tasks such as managing printers, published applications, or user policies. Specialized staff members can carry out their assigned tasks without being granted full access to all areas of server

farm management. SpeedScreen Flash Acceleration SpeedScreen Flash Acceleration allows you to optimize the way MetaFrame Presentation Server renders and passes Macromedia Flash animations to users. Flash animations are a common component of many Web sites and Web applications. SpeedScreen Image Acceleration Using lossy image compression, SpeedScreen Image Acceleration offers you a trade-off between the quality of photographic image files as they appear on client devices and the amount of bandwidth the files consume on their way from server to client. Lossy image compression reduces the size of image files the server sends to the client by removing redundant or extraneous data from the files. Session Reliability Session Reliability keeps ICA sessions active and on the user’s screen when network connectivity is interrupted. Users continue to see the application they are using until network connectivity resumes without re-authentication prompts. Ability to Hide Disabled Applications When you disable a published application, you can choose to hide it from lists of published applications. Hiding the application prevents it from appearing in a user’s Start menu, Program Neighborhood application set, application folder, or taskbar while the application is disabled. This option is useful if you need to temporarily disable a published application while you apply updates or address an issue with the data source. By default, a disabled application continues to appear in lists of published applications. Dynamic Session Reconfiguration This feature creates a smoother experience for users who switch between client devices with varying display modes by reconfiguring window appearance appropriately between devices. When reconnecting to a session on a client device with different display modes, users do not need to reconfigure the color depth and resolution. Dynamic session reconfiguration automatically adapts the existing session’s display mode to the reconnecting client device’s display capabilities and mode preference.

New Features in Installation Manager Installation Manager is included with the Enterprise Edition of MetaFrame Presentation Server. Enhanced Delegated Administration With the new Enhanced Delegated Administration feature, you have greater flexibility and control over the tasks that you delegate to IT staff. For example, the new Install and Uninstall Packages permission allows you to control which servers your delegates can deploy packages to using Installation Manager. Rolling Out Package Groups Using Apputil The apputil command lets you roll out published applications over additional servers. Enhancements to apputil in this release provide the ability to roll out Installation Manager package groups on additional servers. When you run apputil, the package is scheduled for immediate installation on the target servers.

New Features in Resource Manager Resource Manager is included with the Enterprise Edition of MetaFrame Presentation Server, and incorporates the following new features and

�� $� ��

enhancements. Failed Import Alerts Resource Manager now warns you of failed attempts to update the summary database, and can be configured to send alerts under these circumstances. In its red state, a new icon on the Summary Database tab identifies failures to commit the last update to the database. The Summary Database Configuration dialog box now allows you to notify administrators of any such failure. Enhanced Delegated Administration Enhanced Delegated Administration in Resource Manager allows you to delegate the tasks of controlling applications and analyzing system and application data to custom administrators. Compatibility with Asian Language Web Servers In the past, some users of European language versions of MetaFrame Presentation Server Clients could not launch published applications from the Web Interface running on an Asian language Web server. This would occur when the name of the application as it appeared on the Web Interface contained Asian language characters that the European language client was unable to recognize and process. New in Citrix presentation Server Release 4.0 SmoothRoaming for Personal Access Continuity Printing Performance Improvements A new version of the Universal Printer Driver enables MetaFrame Presentation Server to use the Windows Enhanced MetaFiles Format (EMF) for transferring print jobs from client to server. This improves printing performance, especially time to print. You also now have access to more printer properties, such as additional paper trays and finishing options (stapling and sorting, for example). Printing Control Improvements You can now allocate network printers to users through session printers policies instead of through the properties page of the Printer Management node. This enables you to create customized printing workspaces based on any policy criteria without the use of complex logon scripting. When a user logs on to a server, session printers policies determine: • Which network printers to connect within a session • Whether or not a particular printer should be the user’s default printer • Whether or not the user can override default values for common network printer settings When upgrading a prior version of MetaFrame Presentation Server, the installer automatically converts printer settings into equivalent settings in printer policy rules. To administer auto-connect printer objects for servers of versions prior to this release, you can use a Presentation Server Console locally that matches the server version. Further printing enhancements include shorter, more user-friendly client printer names, and dynamic printers and ports—client printers and ports are visible and accessible only within the session in which they are created. USB Synchronization for PDA Devices

��

� �

� ��

�� ! ��"�� #��

You can synchronize a client-connected USB PDA device using application software running on MetaFrame Presentation Server, rather than only through applications on the client device. This feature supports USB-tethered and Microsoft Windows powered PDAs that use ActiveSync as a synchronization agent. PDA synchronization is available in the Advanced and Enterprise Editions of MetaFrame Presentation Server. Redirection Support for TWAIN Devices MetaFrame Presentation Server can now redirect client-connected TWAIN imaging devices, notably document scanners, from the client to the server, regardless of connection type. This allows users to control client-attached imaging devices from applications that run on the server; the redirection is transparent. To capture an image, users connect to a server from a client machine that has an imaging device and the associated vendor-supplied TWAIN driver installed locally. When the TWAIN application is run from within this session, the application detects and interacts with the client-side device. The server-based application that is accessed runs in the way as a client-based application. Redirection support for TWAIN devices is available in the Advanced and Enterprise Editions of MetaFrame Presentation Server. Smart Card Roaming SmoothRoaming now enables users to use their smart cards to log on and off automatically through Program Neighborhood Agent. This is very useful in an environment where employees use computers as terminals that are scattered across a facility. To log on automatically and retrieve applications, an employee inserts a smart card into a terminal. To log off automatically, the employee simply removes the card. To gain greater flexibility when a user logs on and off, use SmoothRoaming in conjunction with workspace control. For more information about workspace control, Application Isolation Environments Application isolation environments solve issues arising from application compatibility and interoperability in the server environment. These issues not only increase total cost of ownership, but can potentially hamper the deployment of MetaFrame Presentation Server on an enterprise-wide level. Application compatibility issues in a server environment can be characterized as follows: Registry conflicts. Applications that do not conform to Microsoft’s guidelines for use of HKEY_LOCAL_MACHINE can cause a number of problems, such as limiting the application to run as a single instance, overwriting the previous user’s settings, an increased likelihood of crashes, or in a worst-case scenario, allowing a user to read the previous user’s credentials. Conflicts can also occur between applications, especially between multiple versions of the same application. DLL versioning. Applications can install a specific version of a DLL in a system folder while another application overwrites that DLL with a different version, causing the first application to execute incorrectly. For most applications, installing a different version removes or conflicts with prior versions. Incompatibility with Terminal Services. Some applications do not run successfully in a Terminal Services environment and therefore do not run successfully on MetaFrame Presentation Server. Incompatibility with Terminal Services is often caused by registry conflicts, system conflicts, and system objects conflicts. Post-installation configuration requirements. Many applications require postinstallation expertise to run successfully on MetaFrame Presentation Server. Extensive testing requirements. The possibility of application conflicts either at

install or run time requires extensive predeployment testing, which is expensive and time-consuming. Maintenance of aging legacy systems. Using and maintaining legacy applications that support essential business processes are crucial in many organizations. Often such applications cannot coexist with modern applications and need to be installed on dedicated servers. Application isolation environments enable you to publish: • Multiple versions of applications on a single server • Applications that were not designed for multiuser or terminal services Environments

Virtual IP Address and Virtual Loopback Address Support Using virtual IP addresses, you can publish applications that require separate IP addresses per session. This is especially important to Computer Telephony Integration (CTI) applications, which are widely used in call centers. If an application you are publishing requires a unique IP address for each user session or requires a unique loopback address, after publishing the application you can configure your server to supply virtual IP addresses or a virtual loopback address. You can use virtual IP addresses or virtual loopback for applications that fail or malfunction when running in multiple, concurrent sessions. Failure and malfunctions usually occur with custom applications that are not intended to operate with Windows Terminal Services. The operational requirements of an application determine whether it requires a virtual IP address or a virtual loopback address. Users of these applications can access them on MetaFrame Presentation Server in the same way that they access any other published application. Virtual IP addressing and loopback addressing are available in the Advanced and Enterprise Editions of MetaFrame Presentation Server.

CPU Utilization Management CPU utilization management increases perceived single-server scalability. It does so by modifying the normal job priority scheduling in the operating system. CPU utilization management smoothes out the normal CPU peaks that most applications have. In a typical deployment running MetaFrame Presentation Server, a certain amount of CPU utilization is reserved on each server to handle these CPU spikes. By normalizing the CPU consumption by each user, the amount of CPU that must be reserved to handle these spikes can be reduced. CPU utilization management also limits very CPU-intensive applications to a limited share of the CPU, so that one user does not inadvertently have an inappropriate adverse affect on other users. CPU utilization management makes the CPU time consumed by users easier to predict. This enables you to better estimate the number of users who can connect to a server and the number of servers that are required. CPU utilization management is available only in the Enterprise Edition of MetaFrame Presentation Server.

Virtual Memory Optimization Virtual memory optimization enables you to improve application performance and virtual memory usage through DLL loading optimization. DLL loading optimization ensures that components of a process load at their preferred base addresses. As a result, overall virtual memory consumption on the server is significantly reduced, providing more room for additional users and applications. The Presentation Server Console contains new options to enable, disable, and schedule virtual memory optimization. Virtual memory optimization is available only in the Enterprise Edition of MetaFrame Presentation Server.

Multi-Language User Interface Support for the Web Interface Language packs are provided to localize the Web Interface into the following languages: English, German, Spanish, French, and Japanese. A language pack allows you to display sites in a given language, including resource files and localized images. You can also allow users to select a language when they log on; the page is then reloaded in that language.

Simplified Customization of the Web Interface You can now customize the appearance of the Web Interface through the Access Suite Console, rather than by scripting or custom coding. Some of the options are: • Overall layout. Customize the overall screen layout or allow users to customize the layout. • Branding. Format the screen with a customized look and feel using branding colors, logo images, and header images. • Applications window. Specify the window title bar color or image, title bar text color, number of application icon columns that are displayed, and allow users to customize these settings. • Welcome area. Specify the title bar background color, title bar text color, welcome message text language, welcome message text, and any additional languages. New in Citrix presentation Server Release 4.5 Configuration Logging Configuration Logging enables you to keep track of administrative changes made to your server farms: which administrator made the change, what the change was, and when it was made. It also enables you to revert those changes if necessary. You can also create a Report Center report that lists these details, and also indicates whether or not the change was successful, the object the change affected, and various further details of the change Health Monitoring & Recovery You can proactively monitor farm health by running Health Monitoring tests on servers to ensure that if one of them has a problem (for example the Citrix IMA Service may be down, or there may be a problem with Terminal Services), this does not interfere with the user’s ability to access the application through another server.

You can specify different recovery actions to be taken automatically if a server fails a test; these include restarting the server or preventing it from being used for load balancing until the problem is fixed. Citrix Application Streaming The application streaming feature simplifies application deployment to users. With the application streaming feature, you can install and configure an application on one file server and deliver it to any desktop or server on demand. Upgrading or patching an application is simple, because you are required only to update or patch an application stored in one place: on the file server Further Enhancements in this Release Alerts storage and reporting. Alerts can now be stored in the Resource Manager summary database, together with related information such as when the alert occurred and which server was affected. This enables you to create a report listing all the alerts that were generated during a particular period of time. Microsoft Operations Manager 2005 support. The Citrix Presentation Server Management Pack now provides full support for MOM 2005 features. Monitoring profiles. Rather than configuring metrics for each server, you can configure a set of metrics, save them as a monitoring profile, then apply that profile to a range of servers. Automatic proxy detection support. Proxy servers can be automatically detected: this means users do not have to configure the proxy server manually. In larger environments, this also means administrators do not have to support incorrect or dynamic configurations. For further information Program Neighborhood Agent backup URL support. Administrators can specify backup URLs for Program Neighborhood Agent in their Web Interface configuration. In addition, if Program Neighborhood Agent cannot connect to the Web Interface, administrators can specify backup URLs in a new .MSI package property. Multilingual user interface. The Windows Installer package automatically installs the clients in all supported languages. Beginning with version 10.0 of the Clients for Windows, language-specific installation packages are no longer available.

How to ADD additional language in Citrix

Luckily for us, it’s easy to add additional languages to WI4. In this article, I’ll show you how easy it is to add Danish or any other new language to WI. All that’s required is a little file editing and some translation skills.

All of the WI4 language files are located on the WI4 server in the "\Program Files\Citrix\Web Interface\4.0\languages" folder.

�� '� ��

� �

� ��

�� ! ��"�� #��

As you can see from the picture above, all you have to do is create a new set of language files from the existing ones. In this picture, "Danish (DK)" has been added. The *.lang files contain the definition of the languages. For example, the "dk.lang" file is a text file that contains the definition of the language in the following format:

FriendlyName=Dansk (Danish)

From here it’s just some hard work to get your own files translated. The main strings are located in "common_strings_languageID.properties" and "metaframe_strings_languageID.properties" files. An example of a Danish translation from "common_strings_DK.properties" could be:

ForMetaFrame=til MetaFrame OK=OK VersionTitle=Citrix Presentation Server Help=Hjælp SelectConnectionSpeed=Forbindelses hastighed: Custom=Tilpasset HighBandwidth=Høj - Kabel/DSL/LAN MediumHighBandwidth=Mellem høj - Modem (>33K) MediumBandwidth=Mellem - Modem (<=33K) LowBandwidth=Lav - GPRS/Trådløs ReconnectTo=Genforbinder til: DisconnectedApplicationsOnly=Afbrudte programmer AllApplications=Alle programmer LogIn=Log på Welcome=Velkommen PleaseLogin=Venligst log på MessageCenter=Meddelelses Center MessageCenter1=Meddelelses centret viser informationer og eventuelle fejl beskeder. Settings=Indstillinger

��

� �

� �

� ��

�� ! ��"�� #��

Refresh=Opfrisk Error=FEJL

The result is as follows (only partially translated so far):

If you want to limit your users in selecting specific languages just remove the files languageID.lang (i.e. DK.lang) for the languages you don’t want your users to use.

If you want to remove the language option all together then just remove all the lang-files except the English one. Now your users won’t be able to select any other language and everything will be in English.

If time permits you can also translate the WI4 help files. The location is "\Program Files\Citrix\Web Interface\4.0\localizedContent." Just create a new language folder, copy the English files into it, and begin translating.
