In trying to publish a web site in my new ISA 2004 installation, I noticed that when I try to tell it to use specified IP addresses on the ISA server, there are none in the list to pick from. I went back to my trial installation running in Virtual Server, and the single external IP address does, in fact, show up there. The web site does not get published, so I'm wondering if these might be related. Guinn Unger
