I have several sites configured in IIS (a separate server), each with its own private IP address. The NIC is configured with each of these IP addresses and the gateway address is the local interface of the ISA server. On the ISA server I have several destination sets 1 each for the sites that are setup in IIS. The URLs/destination set keywords are set1: www.go-vcs.com, go-vcs.com, set2: music.go-vcs.com, set3: inet.go-vcs.com. In web publishing these destination sets are mapped to the private IP addresses as setup in IIS and the nic of that server. The first web-site as defined by destination set1 works great. The second and third, which are setup the same, does not work and now I am wondering if the keyword/header I have setup in set1 (go-vcs.com) is causing improper redirection of the other two? Is there a particular logfile that would be helpful in troubleshooting this problem?
