Was the snapshot made during runtime? Then you maybe have inconsistent
databases in your backup. But if the current live version is completely
broken, I would try that one of course. But only if this is your only
DC. Never restore a DC, if there is at least one healthy is online! The
replication could mix up your AD completely.
If at least one DC is healthy, join a new one and demote the broken
one(s). The problem is, that all ways to demote are currently broken:
- Via Windows: https://bugzilla.samba.org/show_bug.cgi?id=10595
- Via samba-tool: https://bugzilla.samba.org/show_bug.cgi?id=10734
But remember: When you go back to a backup of your AD, then all changes
done in the meantime are lost. And this are not just the obvious
ones(create/delete users, etc.). E. g. all Windows machines change their
machine account password per default every 30 days. So it could be
possible that machines that had changed their passwords meanwhile, have
to be re-joined to the domain.
