95% of the DNS is still out there. :)

Not everyone wants to depend on DNS services 'in the cloud' even if they're
free...

Doesn't going through OpenDNS achieve pretty much the same thing?

FWIW, I load the entire domain list from http://www.malwaredomains.com/ into
my AD integrated DNS without any problems. over 18000 domains are currently
included. I've got a 2003 native domain/forest too. DC's include WS08R2,
WS08, & WS03 SP2. I have not seen anything like this here.

It appears that background zone loading is a feature of 2008 and later...
maybe I just need to hurry up the upgrade to 2008.

Oh! 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.

"Debug logging" will log DNS packets to a text file.  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.

It should be able to kick out more info to a text file.

 

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

Good idea, but the DNS Server's event logging option has been on "all
events" all this time.  That must be the default, I don't recall ever
changing it.

This would seem to indicate to me that while the DNS Server service was
initiated, it never actually finished initializing.

 

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.

Subject: DNS Server service shuts down shortly after the DC boots

 

Curious thing, started a few months ago after I moved the FSMO roles from
this DC to another one.  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!

 

TIA,

Carl
