conf.exe is the NetMeeting executable.
If it doesn't show up on the start menu, you can launch NetMeeting by running conf.exe.
If conf.exe won't run, then NetMeeting isn't installed.... which would be awfully hard to explain, as Slugbait is correct: NetMeeting is installed under W2K, and there's no way to remove it. (At least, not easily.)
Also, NetMeeting is protected by WFP, so it's really hard to accidentally get rid of it.
