Yeah, I've never really gotten the Windows Appletalk server to work that well. However at work we use a program called PC Maclan which does its job quite well, if you want to install it on XP you will need to get the latest version. If you have a linux box lying around you can also use netatalk to do the trick. Actually my setup at home, which consists of 1 linux box, 1 XP box, and a mac, works that way. I have netatalk and samba set up on the linux machine, that way I can transfer files between all three.
