Task "WITs" from Group "WorkItemTracking" failed

Hi,

I have suddenly met the following error when I try to create a new team project on a B3R team foundation server :
(Single server, Active Directory)

TF30162: Task "WITs" from Group "WorkItemTracking" failed
Exception Type: Microsoft.TeamFoundation.Client.PcwException

Any Idea

Hi Martin, I'm having the same problem and I notice that an Active Directory member have been recreated. After that, I cant create new team projects.

Could you be more specific about how to solve this issue I seem to be experiencing the same issue. When I looked at the table, I found two entries for the same person. Did you make the SID the same for both or did you delete one of them

Is this the only way to solve this
