vista and xp networking problems

[ranga_surf]

ive got 2 computer networked through a hub to the internet.
vista can access everything on xp, but doesnt know where to place it on the
map.
xp can see vista, can see its files but cant access them
ive mcafee on both with both firewalls allowing each other connection.
now when i go to a folder in vista to share it, and go into 'advanced share
option' in goes "the program will not run, parameter incorrect". ive read soo
much on this and dont know what to do.
