I thought that you were replacing one existing DC in a multi DC domain,
if so, you do not 'provision', you 'join' a new DC.
Can you please post the exact command you used.

Not sure why you are doing that, if you are going to use Bind9, why not
just join with '--dns-backend=BIND9_DLZ' ?

Provided that there are no records in AD for the DC, you should be able
to use the old hostname and IP.
