sorry when did we establish that it was definitely a pix issue?! all i heard
was that their was a pix in front, that by no means eliminates his dns
servers as a source of the problem..

OK so was there anything in the logs...
have you got two dns servers? do you get the same responses from both if you do an nslookup.

OK - while we were chatting the DNS went down again. I restarted the DNS and its working again.
Maybe a call to MS Tech Support is due -

This actually has happened with and without forwarders -
Steve, I interpret your suggestion as using only the Root Hints?

FWIW.....I have 2 caching only DNS Servers that I setup to use as forwarders for my AD DNS Servers, when I use them, I get the very same issue. If I however, remove them from the forwarders section, I have no DNS Issues at all whatsoever, anytime.

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.
