<Clearing Cache> It that a bat file that you run using scheduled tasks?
Can you share the commands in it with me?
OK that sounded desparate, but I'll take it anyway :)

I think it's a bug in 2003's DNS.. They have the "cache pollution
protection" tick box, but personally I don't think it works.
I created a job that runs every day that clears the cache on the
server(s) affected.

Thanks Mike:
I will try clearing the cache - but this happens now about everyday
(morning usually). I really have to find the source of the problem.

Windows 2003 DNS servers?
Believe it or not, ive seen that . It's a cache pollution type of
behavior, with no logging or other signs to prove that.
Try to clear the DNS cache next time and see if it helps.

Steve: Funny you should say that because I've done that a few times.
DNS stops - I removed the forwards - Restart DNS - DNS works.
DNS stops - I change the forwards - Restart DNS - DNS works.
I want to blame my server but I'm just not sure where the failure is.

Hello All -
This might be off-topic, but has anyone every had their Windows DNS/DC
server intermittently stop forwarding DNS requests?
I checked with the ISP and they don't recognize and problems on their
end.
