Oops. I actually have ICS on the Win 98SE partition of the dual boot SE/XP system. That's the one with the modem. The other machine, SE only, was the remote machine. As I now recall, hopefully correctly, it doesn't have ICS actually running on it.

So the remote machine pings the XP machine successfully but not vice versa. Do I still follow your above instructions? Apologies for making it more complex than necessary.
