Uuuhh, okay. I don't know about any cache/config settings - I looked but couldn't find anything so any advice you may have will definitely go down well. The only possible "dodgy" setting is the fact that I have got the "Do not use recursion" option selected as well.

I am thinking along the lines of cache and such.

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.
