Windows Server 2003: IIS not running aspx pages

Usually indicated by a "page not found" error even though you can get at static files like images, stylesheets, etc.

1. Open IIS


2. Expand Web Service Extensions


3. Make sure ASP.NET v1.1.4322 and ASP.NET v2.0.50727 are both allowed


4. If v2.0 is missing, run:aspnet_regiis -i from the command line to add it
