A server is primarily a program that runs on a machine,

providing a particular and specific service to other

machines connected to the machine on which it is found.

A server is a machine with a specific set of programs that

offer different types of service, which other machines (then

called clients) request to do certain tasks.

For example, a file server is a machine which keeps files,

and allows clients to upload and download them from it.

A web server is a machine that hosts web sites and allows

Internet users (clients) to access these web sites.

A mail server is a machine which, along with the storageand management of email messages, provides service to

email users who can read, retrieve, and manage these

emails messages.

Windows Server 2008 offers two general types of

installations: a typical Full server installation and

Server Core. Server Core is a stripped down version of Windows

Server 2008 that doesnt include a GUI or any other

unneeded services. Instead, the server installs only key features that

are related to the role that it supports (i.e. Active

Directory or Domain Name System (DNS)).

Start the computer and bootup using the WindowsServer 2008 installation media. Select the

installation language, time and currency format,

and keyboard layout and the click Next.

Enter the product key. If you dont want to activate

Windows as soon as youre computer goes online(for example, if you are simply testing the

installation or evaluating Windows Server 2008),

you can uncheck the Automatically Activate

Windows When Im Online checkbox (Figure 3).

Click Next.

Now select whether to install Windows Server 2008Enterprise (Full Installation) or Windows Server

2008 Enterprise (Core Installation). For now, select

Windows Server 2008 Enterprise (Full Installation)

(as shown in Figure 4), and then click Next.

If you accept the terms of the license agreement,check the I Accept the License Terms checkbox

(required to use Windows), and then click Next

(Figure 5).

Select the type of installation you want to perform.

In this case, you are performing a clean install, soyou should select Custom (Advanced). Youll notice

that you cant select Upgrade unless you initiated

the setup from an existing Windows Server

installation (Figure 6).

If your hard drive is automatically detected, you can

create and format a partition as necessary for the

installation. If your drive isnt detected, most likely the device

driver for your controller isnt built into Windows, in

which case you can click Load Driver (at the

bottom-left of the screen) to load it.

Click Next after you have created the partition to

which you are going to install (Figure 7).

Now that Windows Server 2008 has all the basic information it

needs to proceed with the installation, it begins the installation

process and displays the status of the install, as shown in

Figure 8.

This is where setup significantly differs from previous Windows

Server builds, as you will not be prompted for any further details

until the installation is complete and Windows fully starts up.

This is a great enhancement, since you can walk away from theserver while the installation proceeds without having to worry

about additional dialog boxes asking for further information to

complete the install.

All Windows Server builds since Windows NT have been using NT

Loader (NTLDR) & boot.ini to control the boot process as well as

manage multi-boot environments.

With Windows Server 2008 (as well as Windows Vista), the entire

boot process has been re-engineered, resulting in the creation of the

Boot Configuration Data (BCD).

The BCD architecture is a hierarchy, which is exactly why it made

sense to reuse the registry hive format for this data store. It is

composed of three distinct components: stores, objects, and

elements.


30/32

Component:Component:

BCD Store


Top-level component in the

hierarchy. Think of this as

the root of all components

in the hierarchy;

It serves as the starting

namespace for the items it

contains. You can also

think of the store as the

actual physical BCD file.


31/32


BCD Object


In the abstract, this serves

as a container for all BCD

elements.

In practical terms,

information pertaining to

the boot environment for

each instance of the

Windows boot loader is

typically stored here.


32/32


BCD Element


Think of these as

properties and parameters

to the BCD object. Each

element represents one

property or parameterforexample, the name of the

operating system or a

debugger setting.
