Not sure if this will help or not but I have 3 PC's on a network 2 running Windows 98 and the other running XP pro. I put the same user accounts password and log in on all 3 PC's and allowed file sharing. The XP PC was able to see the high level files but not access them. I searched high and low for an answer and it was suggested put NetBui on all the PC's I was only using TCP/IP. Once I bit the bullet and put NetBui on all PC's they all could happily see and share according to the security allowed. I still would have rather achieved this without NetBui though.
