AD DNS

Perhaps you can be of some assistance with a problem that
I'm having?

I'm installing the first server in a new forest/domain.
This forest will have only one domain within the forest
and covers only a single LAN.

The problem is that DNS won't function properly with
regards to AD. I've tried installing DNS in two ways:

1.Prior to promoting the first server to a DC, install
and configure DNS with the forward and reverse lookup
zones, galena.local and 10.200.25 respectively.
2.Leave DNS uninstalled and let the AD wizard handle DNS
during dcpromo.

In either case, DNS fails to populate the domains forward
lookup zone with the SRV records.

Ipconfig /registerdns has no effect

Netdiag /test:dns displays a message that states:
[WARNING] Cannot find a primary authoritative DNS server
for the name pers2.GALENA.LOCAL [RCODE_SERVER_FAILURE]
The name pers2.GALENA.LOCAL may not be registered in DNS.
The DNS entries for this DC are not registered correctly
on DNS server 10.200.25.61.

In DNS there is however a SOA record for the zone
GALENA.LOCAL and an A record and NS record point to
pers2.galena at 10.200.25.61

the ipconfig of the server follows;

Would you happen to be able to shed any light on this
problem?

The problem is your server has no Primary DNS suffix it can't register it
addresses so long as this persists,
What is the domain name in ADUC?
Email it to me directly there may be a fix.
 
The real fix is to give the server a proper name -- don't
use the registry hack since you are just starting out.

DCPromo it back to a Server, rename it, then DCPromo
it back to a DC with a proper name (e.g.,
machine.YourDomain.com

If you don't, you'll be sorry.

In some cases Herb, if you try to demote it, and the Prmary DNS Suffix is
incorrect and the SRVs never got registered, it will be almost impossible to
do.

However, there is a manual method to demote a machine (not supported by
Microsoft), but it works. It's better than reinstalling the machine if it
won't demote.

You could also force the SRV entries from the netlogon.dns file into a zone,
and try that. Did it once that way a long time ago and it worked fine.
