On the "bad" system, you should be able to stop netlogon, remove netlogon.dns, 
start netlogon, ipconfig /registerdns, force replication. That should take care 
of it.

Subject: DNS problems - no glue record found

We put a new DC in one of my sites this afternoon. This is a Win2000 DC, in a 
child domain. My guys added it to the domain, and made it a domain controller. 
THEN they decided to put DNS on it ...

And now I am getting DNS failures, when running DCDIAG.

Testing server: MajorSystems\MJRSWDC003
   Starting test: Connectivity
      MJRSWDC003's server GUID DNS name could not be resolved to an
      IP address.  Check the DNS server, DHCP, server name, etc
      Although the Guid DNS name
      (064ff8f1-0843-4833-bc82-2c41e08a97f0._msdcs.ads.pha.phila.gov)
couldn't be
      resolved, the server name (MJRSWDC003) resolved to the IP address 
(10.64.62.241
      and was pingable.  Check that the IP address is registered correctly with 
the
      DNS server.
      ......................... MJRSWDC003 failed test Connectivity

The weird thing? that record that couldn't be found is not the domain of this 
DC; that indicates the parent domain ...

dnslint says:

CNAME: 064ff8f1-0843-4833-bc82-2c41e08a97f0._msdcs.ads.pha.phila.gov
Alias: mjrswdc003
Glue: Unknown

I can see where to add the CNAME in the DNS of the parent domain, but have no 
clue how to add the GLUE record.

DCDIAG /FIX does nothing to resolve this. They've tried uninstalling and 
re-installing the DNS service, to no avail.

<SIGH> A horrible for for AD for me ...

Anyone?
