We have a single 2008 R2 DC. We're trying to locate Builtin groups that no longer visually appear in the Builtin group folder in the domain tree in the left panel of the active directory users and computers tool. We tried the directory search, thinking that maybe those groups were just moved to another OU or folder and the search found them. However, the search claims that those groups are still in the Builtin folder when they are not.
Can anyone please explain where our "missing" groups actually are or what is going on with the search?
