I have: Microsoft Visual Studio 2008 Team Explorer Version 9.0.21022.8
When I go to Team->Team Foundation Server Settings->Group Memberships;
Double-click on 'Team Foundation Server Licensed Users';
Select "Windows User or Group" in the 'Add Member'; In the "Select Users, Computers or Groups" type in the group name, then 'Check Names', resolved, press 'OK'.
Now I can see the group added to the 'User or Group' list.
Unfortunately, when I press 'OK' I get the following unhelpful message
Microsoft Visual Studio
Team Foundation Error
MyGroup
OK Help
(where 'MyGroup' is the name of the Windows group I was trying to add).
At the same time, though, adding individual users from that group works fine.
Any ideas on where to begin with this error (pressing 'Help' shows the 'Information not Found' page).
