Hi John If you believe that it could be a config issue, let me tell you my config: - DNS installed on 2 Domain Controllers - FW Client installed on both DC's - DC's also setup as SNat clients - DNS configured to use 2 forwarders provided by my ISP I can 100% reproduce the problem simply by restarting my Firewall Service, then my DNS fails on the DC's and I have to restart DNS to resolve the problem.

Let me poke around in mine in the morning and see if I can find anything.

But my main problem is that when my Firewall Service is restarted, my 2 DNS Servers "lose their connection" and thus have to have DNS restarted before they are then able to perform lookups etc. I don't think this is an ISA issue though.
