In news:O%23iibS0GEHA.2576@TK2MSFTNGP11.phx.gbl,
Robert Cohen <dont@want.spam.com> posted a question
Then Kevin replied below:

Actually the 127.0.0.1 is part of the problem, it is the DNS address on the
dial in adapter. This adapter will configure itself . What you can do is
configure the listener address on the DNS server (interfaces tab) to listen
only on 10.0.0.2 then disable and re-enable the Dial in adapter, IIRC that
will cause the dial in to adopt 10.0.0.2 as its DNS server and keep DNS from
trying to register the 192.168.234.235 record.
Another problem with multihomed DCs is all the Blank (same as parent folder)
records, DC's will automatically try to create a blank record for each IP
address on the DC. In truth the only blank record you should have it for the
adapter that is at the top of the binding order and has file sharing bound.
But I see a big problem,
DNS test . . . . . . . . . . . . . : Passed
Interface {C2996A6A-0D4E-44DA-AE5D-42C633427EAF}<--Default adapter
DNS Domain:
DNS Servers: 10.0.0.2 10.0.0.3
IP Address: 10.1.0.2
Expected registration with PDN (primary DNS domain name):
Hostname: bbh01.baltimorebehavioralhealth.org.
Authoritative zone: baltimorebehavioralhealth.org.
Primary DNS server: bbh01.baltimorebehavioralhealth.org 10.0.0.2
Authoritative NS:10.1.0.10 10.0.0.2 10.0.0.9 10.0.0.3
Interface {EC320E1B-7263-401F-9D72-D1D93918D38C}
DNS Domain:
DNS Servers: 10.0.0.2 10.0.0.3
IP Address: 10.0.0.2 63.141.72.67<---This interface has IP addresses
on different subnets, one of which is a public address. The problem with
this is if you bind file sharing to this you are binding file sharing to a
publicly available interface. Not good!
What interface is upposed to be your private internal interface?
That is the interface that should have its addresses registered in DNS, it
should also have file sharing enabled on it.
Expected registration with PDN (primary DNS domain name):
Hostname: bbh01.baltimorebehavioralhealth.org.
Authoritative zone: baltimorebehavioralhealth.org.
Primary DNS server: bbh01.baltimorebehavioralhealth.org 10.0.0.2
Authoritative NS:10.1.0.10 10.0.0.2 10.0.0.9 10.0.0.3
Interface {B47C4124-6D9C-4768-AF33-9574AA936399}
DNS Domain:
DNS Servers: 127.0.0.1
IP Address: 192.168.234.235
Expected registration with PDN (primary DNS domain name):
Hostname: bbh01.baltimorebehavioralhealth.org.

Verify DNS registration:
Name: bbh01.baltimorebehavioralhealth.org
Expected IP: 10.1.0.2 10.0.0.2 192.168.234.235
Server 10.1.0.10: ERROR_NO_MATCH
Missing IP from DNS: 10.1.0.2 192.168.234.235
Server 10.0.0.2: ERROR_NO_MATCH
Missing IP from DNS: 10.1.0.2 192.168.234.235
Server 10.0.0.9: Error 1460 ERROR_TIMEOUT
Server 10.0.0.3: NO_ERROR
[WARNING]: The DNS registration for
'bbh01.baltimorebehavioralhealth.org' is correct only on some DNS servers.
Please wait 15 min for replication and run the test
again.
Check the DNS registration for DCs entries on DNS server '10.0.0.2'
The Record is different on DNS server '10.0.0.2'.
DNS server has more than one entries for this name, usually this means there
are multiple DCs for this domain.
Your DC entry is one of them on DNS server '10.0.0.2', no need to
re-register.
