I have 2 DNS servers on my Internal Network and they are using Forwarders to my ISP's DNS. I have now added my ISA 2004 server and setup DNS cache on this system. Now my internal forwarders are pointing to the ISA server and the ISA Server is forwarding to my ISP's DNS. I am wondering where the DNS on the Internal Network Interface should be point. I had it pointing to itself and I wasn't able to browse my domain in ISA Manager. I since have changed my DNS address on the Internal Interface to point to my internal DNS and now I am able browse the domain in ISA Manager but, I get NSlookup errors. What can I do?
