How to: Rename a Server-Level Group
You can choose to rename a group to better reflect its purpose. To rename a group, you must have read/write permission to the group you are renaming. You cannot rename the default server-level groups, such as Team Foundation Administrators.
To perform this procedure, you must be a member of the Team Foundation Administrators group. For more information about permissions, see Team Foundation Server Permissions.

You cannot rename default groups.
In the Team Foundation Server Group Properties dialog box, in the Group Name box, enter the new name for the team project group.
