Why do features like FrontPage Server Extensions, WebDAV publishing, ASP, and server-side includes not work on IIS 6.0 by default?

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1

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. You can serve dynamic content and unlock these features using IIS Manager. See Configuring IIS 6.0 Web Service Extensions.
