I have been trying to setup a small network in my home with 1 pc with win xp sp1 and the other with win 98 se

The problem I am having is when i try to access network neighborhood on the 98 machine it just sits there and searches and never finds anything?Before I started accessing the 98 machine i was at least able to see an icon ENTIRE NETWORK with the xp machines name there also but since i have added a few folders to be shared i get nothing??? The other problem that i have if i put a password on my shared files from the 98 machine and try to access them from the xp machine i put in the password hit enter and it dissappears for a second then reappears as if i never pushed enter and does not allow access but there is no message just no action?I have internet access on both machines through a linksys that works fine..just can not access the xp machine from the 98 machine??

any help would be greatly appreciated....thanx
