Hi to all,

a few days ago I wrote that when doing a recovery of an AD with bind9 as
DNS-backend I had the problem that all revers-zone had no NS-record so
the bind9 would not start. After switching back to the internal
nameserver, creating the NS-records, then switch back to bind9 it worked
Today I had another problem with missing NS-records
An Activ Direcory with several DCs all DCs using bind9 as DNS-server. We
removed the first DC we setup when provision the AD a long time ago. Now
all DCs are missing the NS-record of all reverse-zones, the
forward-zones are still ok. So we had to switch to the internal DNS on
one DC recreate the NS-record for all revers-zones then switch back to
bind9 and everything was good again.

This can't be normal!

We now just put more DCs as NS-record in every revers-zone. I would say
it's a bug.

Anyone else had this problem?
