While on the phone with MS PPS - I asked (twice) him to consider the PIX501 (while providing them full access to its logs and dashboard) as the source of the problem. They consistently put that possibility to the side (in reserve) and opted for the (disable EDNS) move. We'll find out in the next 24 hours if he was right.
Side Note: When the cable guy came to run/install the co-axle cable, he went into the attic and ran into a 5-foot black snake slithering between the rafters.

Why do your internal clients need to resolve DNS directly? I never
from.use forwarders on my AD boxes. I always create root zones on my AD DNS servers and only use ISA to resolve DNS for web proxy/fw clients.
That's where what I consider "true" security and separation comes
same

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

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.

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
