We recently installed Active Directory services on a member server (small client that has only 1 server). Everything went fine (dcpromo and all that good stuff). This is Windows 2008 R2 Standard.
For several weeks everything was fine, then Active Directory Services stopped. If you try to restart, it fails, yet nothing is logged in the Event log. Very puzzling. DNS has no entry for the domain. If I try to run Dcpromo again, it does list the domain.local that was present, but can't start it again (since there is no DC to query). tried to regtlibv12 actieds.tlb to no avail.
