Hi Ray, Why is there a DNS server on the ISA Server? Is it a caching only DNS server? Thanks!

Basicly 2 DNS servers on the outside and the DNS/ISa as the gateway.

Your ISA Server is in integrated mode and is your gateway to the Internet. The ISA Server is the standard secondary DNS server to the primary in the DMZ segment between the router and ISA Server. You also have some Web servers and stuff on the internal network. Getting close? Thanks! Tom
