Do you get any further information if you run ipconfig /displaydns to show the
contents of the local cache on the Exchange server? I'm guessing probably not if the
DC/GC resolves by name, but it's worth a try.
Quite a while back Stuart Kwan posted on the list suggesting that all AD
implementations should use properly registered DNS names, even if only used
internally. I guess to avoid the potential problems you hint at, but also in the case
of mergers and acquisitions.
Can you post some of the ADC event log errors?

Ran into an interesting situation this week, a client who had a previous
consultant set up their small AD and the previous guy assigned it the
domain name "honolulu.com" which is, of course, a domain name out in the
world. Problem is...it's not their domain name. They have two servers
- 1 Exchange server and a GC/DC which also (against my advice) is their
ISA server. The GC/DC is Win2000, the Exchange runs Win2K3.
Their Exchange server is having difficulty starting up, LDAP errors that
hint at DNS problems and I'm wondering if the issue is that internal
domain name. The event viewer is full of MSADC errors that say the LDAP
server is down. I suspect that maybe it's trying to connect to the LDAP
server at the public honolulu.com domain.
Their internal DNS seems properly configured and does correctly list
their DC/GC server. We can ping the DC/GC from the Exchange server by
name or IP address. But Netdiag's DNS tests fail when run on the DC/GC
server.
If we start the Exchange server it basically hangs at the "Applying
Computer Settings" stage. None of the Exchange services start up, due
to the LDAP errors, apparently.
I've been Googling but I have a feeling I'm looking in the wrong places.
Any thoughts?
