Filesharing betwen 98SE & XP Home?

I have three computers in my house, my computer's running XP Home (didn't know that you could get Pro OEM edition for about the same price when I purchased), my mom's laptop is also running XP Home, and the family computer is running 98SE. Back when I was running 98SE on my old system, filesharing was always pretty flaky between the family comp and mine, and when I installed XP it just plain stopped working. A few weeks ago I tried to do some filesharing after I installed the networking update (off the XP CD) that is suppost to allow 98 to fileshare with XP, but it didn't work. Does anyone have any ideas? I haven't tested filesharing between the XP laptop and my machine but I'm going to be doing it ASAP.

Just use you XP disc to set up he network on every machine.

Grr! The laptop can't see my system, but I can see it. And I can't access it!

Yes! I got the filesharing (& printer sharing) to somehow work! Now to see if I can get the 98 machine to play nice.

EDIT: I've got them all working now! I just need to keep ZoneAlarm closed.
