Issues when Approving TFS task Changes

Dec 19, 2008 at 5:31 AM
I'm running a single server configuration with Project Server 2007 and TFS 2008 on Windows 2003.

I'm able to create tasks in Project server and automatically synchronize them with TFS, but if I update one of the project fields in TFS (Remaining work and/or completed work) and then Approve the change to send the data for the the work item to Project Server, it fails and I get the following error in the event log

I have looked at the FAQ where you outlined 401 errors and issues related to siteGuid and SSPUrl. I performed all the steps mentioned in the FAQ related to 401 errors but i still get the above mentioned error when i try to approve TFS task changes from PSTFS connector. I keep getting this 401 unauthorized access errors.
