Over the weekend I was practicing setting up the our ISA server....which is hopefully going to replace our hardware firewall. I got as far as configuring the outbound access when I had to quit I shut the machine down and removed it from the network ( disconnected from the LAN and the WAN and reconnected our firewall. This morning, I had a report that a remote user could not access email thru WebAccess. I went to IIS manageron our exchange (5.5) server and discovered that the default web site was stopped. When I tried to start it, I got an "address in use" message. Q261194 in the KB says that there is another service or app listening or using port 80. As instructed, I downloaded and ran Foundstone's utility....which did not come up with port 80 at all. Anybody help me out with this?
