Hey, For the moment, I don't use or know the Microsoft ISA Server at all. If I'm going to implement it, depends mostly on the answer(s) to my question. First, let me explain what I want. I've got a W2K Terminal Server installed. Some of my Terminal Server users may browse the Internet, some don't. That's why some have an Internet Explorer Icon while others don't. But, those who has Internet Access, their activity must be logged on an individual basis. The firewall I've implemented now, can log the Internet to and from the Terminal Server (IP address), but cannot distingiush which user is doing it. This also isn't possible when I implement Authentication on my existing firewall for my TS users, as he automatically assign the source IP in a dynamic access-list as a result of a succesfull authentication. My question now is: "Can I log Internet activity on an individual basis (i.e. user account) for my TS users using MS ISA Server? Take in regard that if I'm going to install ISA Server, it will be on a seperate machine." If yes, I'm won for the ISA Server. Any help is welcome, and I already want to thank you for your answer(s).
