If Windows domain control doesn’t work, if the SYSVOL won’t populate and the NtFrs service has been “scanning” the system volume for a while, try a non-authoritative system volume restore, which is type D2 here:
There is an authoritative system restore too, but that is listed as a last resort.
If an NTFRS service restart does not bring back the domain controller capability, if the SYSVOL share never comes back, the Jet database may be corrupted. This database will be automatically recreated if you do this:
- NET STOP ntfrs
- Rename the folder “C:\windows\ntfrs\jet” to jet.OLD
- NET START NTFRS
