I am having the same problem. I have 2 computers both using XP pro. I have a Linksys WRT54G router. Both computers are accessing the internet okay, but I can't seem to share any files between them. I keep getting the same error that everyone else here is getting.
I tried Ross' fix but that didn't help. My main computer can ping my remote computer, but not vice versa.
