This problem occurs when one of the following is true:

• In Windows Server 2003, you install Internet Information Services (IIS) after you install the Microsoft .NET Framework 2.0. In this scenario, the ASP.Net extensions for IIS are not registered in the IIS metabase.
• In Windows Server 2008, the Web Server (IIS) role is either missing or does not have all the necessary components installed.
