Hi, I've got an install to do at the weekend, replacing a Proxy 2 server. The company use Proxy client and have quite an extensive internally routed WAN. I've seen the Proxy 2 client work with an ISA server. Am I right that the Proxy 2 client uses port 80, ISA client uses 8080? Will the Proxy 2 client reconfigure itself for a change of port if the ISA server replaces the Proxy 2 server on the same IP address? If not does anyone have any ideas how I an avoid (in the short term) visiting every machine? Change the port on the ISA server? Many thanks, Iain.
