We seem to have an issue with out Team Foundation Server 2010 installation that gives an error when certain users are queried. If we include them in the 'AssignedTo' filter the query instantly errors with:
TF237161: Server operation timed out or server not responding. Try again.
For other users this works fine, and the TFS' assigned to these problematic users are returned in the results of working queries. I've checked and it doesn't appear to be a permission problem. We had migrated from Team Foundation Server 2008 to TFS 2010 last year, but the people this is affecting think it was happening before this anyway.
Does anyone have any ideas of where to begin troubleshooting this? I have full access to the server and database, and have started trying to replicate the query in SQL to see if it's an error in the database, but haven't got very far so far.
If anyone has any suggestions they'd be greatly appreciated! Thanks
