windows xp home edition networking woes

Ok this isnt really my problem, I have to say that so I don't get shunned for installing xp home :) .

Ok, here's the problem. My uncle has a network with 5 win98se boxes conecting to the internet through a gateway. He set up XP home on one of the boxes, set up the network to go through the gateway, set up the ip/dns/etc and now it can see all other computers on the network and browse them just fine but the 98se boxes cant see eachother or the xp box. Any suggestions?

fixed it disable the authentication thingie with the drop down on the authentication tab in network properties
