Hello, it's me again. :-) I set up this server as a caching only DNS server following the instructions in the ISA Server 2004 book by Dr. Tom and I can access the Internet on this server, but not on any of the internal computers. I get the "Can not find server or DNS error". I can ping the router through this server, but can't get anywhere on the Internet. Everything works fine through the old ISA 2000 server, but when I switch over to the new one you can't go anywhere. Would someone please point me in the right direction to resolve this matter? Thank you, Barbara Causey
