I am running SBS 2000. I recently aquired an Internet connection using a Direcway satellite connection. The Direcway software has a special piece of software for accessing a proxy server at the Hughes network operations center to speed up satellite latency issues. When I have ISA server turned off I am able to direct my client browsers to port 83 rather than 8080 and have them take advantage of this software. If I turn ISA server on then my clients can't hit port 83, including the browser directly on the server machine. Somehow ISA seems to take over port 83 or shut it down. Anybody run into a simular problem with other software? Andreas
