I have a laptop at work that has both a 10/100 port and a wireless card. I have both connected when I am docked, but when I go somewhere I disconnect the wire so I just have the WLAN connection. I connect to a UNIX machine, and when I un-dock I close all my sessions so the connection isn't dropped. Is there a way under Windows 2000 to determine which network connection a particular application/telnet session is using? I haven't found any built-in utilities that do that, I can only see that there is traffic on each one. Thanks!
