Hello Jim, Apolozing for approaching you directly instead of waiting for my turn. (Actually I did post this question, but haven't receive any replies yet). I have a couple of ISA servers running in "cache mode" (due to not having 2 NIC, one facing external and the other facing internal). I'm using "web publishing" to do redirect the request to an internal web server, my destination set is set to "all destination". When I typed in my ISA server IP address (External representation at the DMZ firewall), I get "can not find server or DNS". What am I missing? Please help! :) Thanks, Sunnie
