What version of Windows is this running on?

Yes, now that you say that.... I bet what's happening is that it's timing out. There is a flag (and I'm sorry that I don't remember the details) that says "do the initial zone load in the background". You probably need to set that. That should be enough to biggle with...

I guess the last DNS packet received before the shutdown could tell me something if it was shutting down randomly at any time. But the fact that the service stays running forever after restarting suggests that bad DNS packets on the wire aren't likely causing this. So if bad DNS traffic is the problem, the only explanation would be a DNS query from the DC to itself. DC DOS's its own DNS server service? One thing I may have that is less common is a lot of DNS authoritative zones for well known bad (malware hosting) domain names. There's over 1000 of 'em. I have to say I'm not up for an extended debugging journey on this one, just wondering if this behavior triggered any memories for anyone.

The scenario you mention of branch DCs not having connectivity is completely normal.

That must be the default, I don't recall ever changing it. Carl From: Michael B.

Aren't there some logging options on the DNS server property tab? I'd probably ratchet those up to max for a while and see if they helped gather more info... Regards, Michael B.

This DC frequently boots "in a vacuum" - no other DC's can be contacted, so it takes a long time sniffing around before it finally starts Active Directory and its own DNS Server service. A few minutes after that, the DNS Server service shuts down. There's nothing in the System or Application event log to explain it, and the DNS Server event log records simply that " The DNS server has shutdown." (event ID 3). The recovery options are set to restart the service, but that doesn't happen because the service appears to have been shut down on purpose. But no human (for sure) and 99.9% sure no software is issuing the command. Another interesting thing from the event logs, under System, when I start the service there's an event 7036 logged "The DNS Server has entered the running state". But I see NO event 7036 for DNS at the time of booting. Obviously, it must be started, else the DNS event log wouldn't record that it had shut down! And I see no 7036 events for it stopping either. When this happens, I can manually start the DNS Server service and all is well until the next boot, which may or may not have the problem. I think it's happening about 50% of the time. I've scripted a solution to recover from the problem, but I'm just curious if anyone has noticed something similar. I'm guessing the instances of branch offices booting their DC without network connectivity back to the FSMO holder at HQ is fairly rare, but not unheard of. And this is Windows 2003 SP2, native 2003 domain/forest. Almost left that off, yikes!
