    1. check whether your IIS is running.

    2. If you are using IIS 6 (that comes with Windows 2003), go to Internet Service Manager -> <<Your Computer>> -> Web Service Extensions and check whether ASP.NET is Allowed or Prohibited. In case it is Prohibited, change it Allowed.

    3. In the Internet Service Manager (InetMgr), check where your "Defautl Web Site" is pointing to. Generally it should be pointing to C:\Inetpub\wwwroot.

    4. It may be also a case of port 80 getting used by some other applications. To check whether this port is used by some other applications, stop the InetMgr, go to command prompt and type the following line

    telnet localhost 80

    If this goes fine that means some other application is using this port. Try figuring out what application it is.

    These two steps will help u solve your problem.

    1. Re-install IIS
    2. run aspnet_regiis in .NET command prompt

    This works fine

    aspnet_regiis should be used when your IIS is not aware of .net framework itself. Going by the error message, I just have a feeling it may not be a problem of that kind.

    Re-install IIS
