If I however, remove them from the forwarders section, I have no DNS Issues at all whatsoever, anytime.

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. -----Original Message----- From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of ISA Sent: Wednesday, October 18, 2006 10:59 AM To: isalist@xxxxxxxxxxxxx Subject: [isalist] OT: DNS and Forwarders http://www.ISAserver.org ------------------------------------------------------- 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.
