http://www.ISAserver.org Hi Mark, It happens from time to time. Check your non-connected UDP mappings and see if they peak right before this happens.

I have my internal DNS setup as a forwarder and allowed DNS communication on ISA. Every now and then the DNS dies resulting in Secure NAT clients not able to resolve external addresses. First I thought this could be caused by my testing on the ISA server but I found out that this happens even if I don't touch anything. I applied all necessary updates and SPs and checked KB but without success. Any idea??
