I have a browser-based ASP application that runs on IIS6.0 over a MS SQL 2000 server. I'm now at a point where I need to track each terminal on the intranet by IP (or rather, MAC address). I've not been able to find information on how to gather the client IP or MAC using ASP server objects or HTML/Scripting, etc. I'd like to avoid having to write an ActiveX control if at all possible. (My client is extremely light, currently with no ActiveX or Java plug-ins... I'd like to keep it that way) Can anyone help? Thank you!
