How to resolve Server Error HTTP Error 404.3 - Not Found error

Server Error in 'Default Web Site/MyWebApp' Application.


HTTP Error 404.3 - Not Found

    Internet Mail Extensions (MIME) map policy that is configured on the Web server. 
    The page you requested has a file name extension that is not recognized, 
    and therefore is not allowed.

Notification: ExecuteRequestHandler 

Module: StaticFileModule							

Microsoft has done really good job in showing detailed error messages and steps to take to fix the issue. Kudos to IIS7.0 team on this! So if you read the error message you will find out what the problem is. Clearly I have not configured web server to handle ASP.Net extensions or for that matter I may not have configured it to handle most of the dynamic frameworks like ASP, CGI, etc. In my previous article Windows - Add Remove Program I showed how you can install or enable IIS on your system. There is one more step involved in enabling ASP.Net on your Windows machine. Follow the procedure in previous article to get to Panel for Windows Program and enable the appropriate sections under Internet Information Services > World Wide Web Services > Application Development Features. If you enable ASP, ASP.Net, Server Side Includes etc., your settings may look like the following image.
