Overview

Benefits of Web servers and IIS Different Versions of IIS IIS 6.0 Architecture IIS 6.0 Enhancements IIS vs. competitors

Why do we need Web Servers?

Rapidly increasing communication speed The use of multipurpose servers The delivery of dynamically generated

information Explosion of intranets

Benefits of using IIS

Enables organizations of all sizes to quickly and easily deploy Web sites

Provides a high-performance platform for applications built using ASP.NET and the Microsoft .NET Framework

Reduces the total cost of ownership through easier server management and server consolidation

Benefits cont.

Increases the security of information systems Delivers a platform for improved developer

productivity

IIS Features

Sharing InformationCreating Web-Based

ApplicationsBringing Server Operating

System Functionality to the Web

Sharing Information

Support for Multiple Sites with One IP Address

Administrators can use Simple Mail Transfer Protocol (SMTP) and Network News Transport Protocol (NNTP) Services to set up intranet mail and news services that work in conjunction with IIS.

The File Transfer Protocol (FTP) service, used to publish information to a Web server, provides a faster, smoother way to download Information from the Internet.

Creating Web-Based Applications

Microsoft Active Server Pages (ASP) provide standards-based database connectivity and the ability to customize content for different browsers. It also provides error-handling capabilities for Web-based applications.

ASP has a new feature for determining the exact capabilities of a browser.

Bringing Server Operating System Functionality to the Web

Integrated Setup & Upgrade

- IIS 5.0 installs as a networking service of Windows 2000 Server. Customers with any existing version of Windows NT Server 3.51 or 4.0 will automatically be upgraded to the new Web Services and can take advantage of the new features and services of Windows 2000 Server and IIS.

Bringing Server Operating System Functionality to the Web (Cont.)

Reliable IIS Restart

- Users can stop and restart all Internet services from within the IIS Microsoft Management Console (MMC) snap-in, which makes it unnecessary to restart the computer when applications become unavailable.
