Hello everyone, It must have been a long brain frying week, I'm having a hard time figuring this one out today...if someone could give me a push I would appreciate it!! I have a user that is trying to get to a password protected website and the URL has the extension ".stm". I have ISA set up fairly tight so of course this traffic is not getting through, we receive "401.1 Unauthorized: Logon Failed" but when I allow All Protocol Rules it gets through fine. I have HTTP, HTTPS, ICA, FTP, etc allowed in the Protocol Rules properties but I also have the ".stm" set in the content groups so I thought it would pass through. Viewing the connection using TCPView I see that the connection is HTTP in which is allowed..... Any ideas?? Thank you!! Rick
