Deploying .Net Application in Windows Server 2003

In order to take a more proactive stance against malicious users and attackers, IIS is not installed on members of the Microsoft® Windows® Server 2003 family by default. Furthermore, when you initially install IIS, the service is installed in a highly secure and "locked" mode. By default, IIS serves only static content — meaning features like ASP, ASP.NET, Server-Side Includes, WebDAV publishing, and FrontPage® Server Extensions do not work unless enabled. If you do not enable this functionality after installing IIS, IIS returns a 404 error.
