Win98 disconnects from Server2003

I have 2 workstations that still use Win98. The
connection between the workstation and the server
disconnects (mostly it seems when they try to print
information from the web). I can't remap the network
drives, or even ping the server. Rebooting the
workstation seems to work as a quick fix.
I found the workarounds on the microsoft site but I am
having a tough time getting anything to work.

Thanks for any help.
