Please also make sure all the clients’ DNS point to the internal DNS server. And the internal DNS server should use forwarders to point to the ISP’s DNS servers. Then you can create access rule to forward DNS request to ISP.

Except for SBS, everytime I see it done it is amess.Get DNS (regaurdless of the method you are running it as) off of the ISAbox. Point the ISA, and every other machine on the LAN, at the AD/DNSmachine for DNS. Then use the ISP's DNS IP# in the Forwarders List on theAD/DNS.Create an Access Rule for outbound DNS Queries for the AD/DNS machine tomake anonymous outbound DNS Queries as a SecureNAT Client.You do that and it will work.
