When you create a new team project in Microsoft Visual Studio 2005 Team System, the project is not created. Additionally, you may receive the following error message in the log:
Exception Type: System.Net.WebException
Exception Message: The request failed with HTTP status 404: Not Found.
WebException: Response Status Code: NotFound
WebException: Response Status Message: Not Found
WebException: Status : ProtocolError


This problem occurs because Microsoft SharePoint Portal Server 2003 returns incorrectly formatted data. The incorrectly formatted data violates strict protocol checks in the Microsoft .NET Framework 2.0 on the client computer.


To resolve this problem, make sure that the Devenv.exe.config file contains the following section.
                  <httpWebRequest useUnsafeHeaderParsing="true"/>


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
