We are in the process of testing ISA in our environment and currently have 4 ISA Servers configured as Standalone, Integrated systems using Windows Load Balancing to provide load balancing and fault-tolerance to the machines. Two of my servers allow anonymous web connections through, while two prompt Netscape clients for a username and password. We want the user to be prompted for their username/password when using the web service, so we can track outgoing requests by userid. I can't seem to figure out the difference between the machines, and have even tried copying the configuration from one machine to another. I am just about to un-install and re-install the software - any other suggestions?
