Desperate: Add a user to the Team Foundation Administrators group
I dropped the BUILTIN\Administrators group from Team Foundation Administrators group and now I can't do anything in TFS. I was trying to exclude all the administrators of the box from showing up in Work Item Assigned To field.
I'm a member of the Administrators group on the box. How can I add myself back to the Team Foundation Administrators group?
Edit: I tried tfssecurity.exe but also got the same error: TF50309: You do not have sufficent permissions to perform this operation.
