On the ISA box How is is it configured to resolve internet host names? Uses forwarders to ISP's DNS servers What protocol rules do you have in place to support it? - Send / Recieve UDP 53 - Recieve / Send UDP 53 - Outbound TCP 53 - Outbound TCP 43 (whois lookups) Where are you doing the nslookup queries from? Useing a SNAT client machine with admin priveledges. I played with the recursion and it will do lookups now. Thanks Thomas..
