[Samba] Problem with Samba4 DB

[mathias dufresne]

Is this the only DC involved in that issue? If yes I would stop the service
on that DC the avoid contamination of others (I don't know if this issue
can propagate but I'm sure I would learn if it is in prod ;)

In prod, what you really want is your AD works. No matter which DC is FSMO
nor if some DC get reinstalled. Remove the DC from your AD to limit risks,
investigate later if you wan to, repair first but repair AD, not the DC.

Then I must admit you have AD as you speak DNS.
Perhaps you are running internal DNS, in that case you can only push DNS
modification on DC declared as SOA in LDAP DB. If broken DC is SOA, it is
also certainly FSMO, move FSMO and SOA on some other host (you can stop
broken DC first, no matter).

If you are running BIND9_DLZ DNS back end you can simply change your
clients DNS resolver to use another DC, as Bind + DLZ knows it can modify
it's DB (its zones) every DC using Bind + DLZ as DNS back end would reply
they are SOA and so they all will accept DNS modification requests.
