There's an article for DNS and ISA that illustrates many (not all) combinations, depending on your particular needs. http://www.isaserver.org/pages/tutorials/dns-4-isa.htm Short story: The DNS server that external hosts use to resolve your external names has to be a physically different machine than the one that resolves internal names for internal hosts if you want to create an "internal" version of the "external" DNS zone.

I don't quite understand. We are setup that the Internal DNS Server/Web server does all DNS lookup for internal clients and this server itself. The ISA server does it's own DNS lookup Both systems point also to our ISP servers for lookups as additional DNS servers. What am I doing wrong??? Thanks very much for your help.
