Networking 98se to xp home

Hello I have 1 98se and 2 xp home computers. I can ping all computer from
each other. the xp home computers see the entire network they can browes
files and folders of the 98 computer but the 98 computer can not see any
computers. it worked fine until i tried to map a peachtree program from the
98 to the xp home. I saw the companies and it worked until I rebooted the 98
computer and then it lost the entire network. If anyone can help me I would
be very grateful
