Thanks Wayne, I missed the 6.2 part.
Back then, I think there was a command that would bring up a curses based (it shows in console--it's sort of like console but had a blue background) thing to configure your network. I'm afraid I've forgotten the name, you can try typing net and hitting the tab key--probably something like net-config netcfg or something similar. If you get that command, it should give you a dialog box to change the settings.
However, I could be wrong--I haven't used 6.2 in--hrrm, 7 years or so?
