Can’t network Xp prowith 98 SE or me

I am trying to setup a small network to share printers and files. The win2000 pro and the xp pro see and share both ways the win98 can see and share with the win 2000 both ways the me can see the 2000 and the win98se. The problem seems to be networking with the me and the 98se to the xp pro I have tried everything I can think of. Any suggestions. I am using a 4 port netgear,switch,firewall print server.

Thanks
