Hi All I changes the internal IP address on the ISA box after stopping the ISA services and then recreated the rules using the new IP address. The ISA server is configured for server publishing. Infact I also rebooted the server. But looks like no connection on port 80 are originating from the internal ip of the ISA to internal web server. I changes the routing rules and also created the rules for the changed IP address. When I try to telnet to internal IP of ISA on port 80, it doesn't answer. SO looks like its not listening on port 80. Any help is appreciated. Its really critical. I just have one more hr left to configure it.
