We seem to be having a lot of problems related to "forgetting some mundane detail" while managing our Group Policy settings in Active Directory, so I am curious as to whether there are any well-regarded tools available for applying source control style practices to Active Directory configurations.
It seems like there should be a way to quickly and easily run a diff against a known-good configuration to figure out what setting changed (or did not replicate to a remote server) and is thus causing problems.
