Solution: ASP.NET Development Server is not working.

Problem: ASP.NET Development Server gives one of the following errors when you try to run your web application.

  1. 404 error though the web pages are there in your application
  2. Cannot find server or DNS Error
  3. Timeout error

Solution to this problem is to disable the NTLM Authentication for your web application. NTLM authentication is enabled by default for your application.

To disable the NTLM Authentication, follow the steps below

  1. Open your web application in VS 2005
  2. Right click on your web application and select the property pages
  3. Go to Start options
  4. Go to Server Section
  5. In that, disable NTLM Authentication.

This workaround will work most of the time.

I am still thinking why NTLM Authentication is not working even in IE forASP.NET Development Server.
