We were given a backup of a collection in TFS 2010 that was turned over to us. I loaded it and I can see the projects in TFS, when I try to access the projects i get the below error. I currently have collection admin rights and project admin rights. Any ideas on how to correct this.
TF201072: A user or group could not be found. Verify that the users and groups used in your work item type definition have been added to Team Foundation Server.
I thought originally that the AD sync didn't work when i added myself to the admin groups so I detached and reattached the collection.
