IIS is not required for ISA to work. If ISA is the only app on the box, then do not install IIS on a new build, which is what I did, or disable it on an existing server. If you need to run IIS on your ISA box because of resource (money, equipment, etc.) issues, then that's another story.

We have the same problem due to IIS running on port 80. If I remember right, you have to have IIS installed for ISA to work. We have our own intranet website on port 80.

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? ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: blewis@xxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: artdekneef@xxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
