I have attached my Dell Laptop running XP Professional., SP2, to my home
office network. The Dell is attached to a router, which in turn connects to
an enthernet hub. There is a HP Laserjet 4050 printer attached to the hub,
and a Mac G4 running OS X 10.3.6 is attached to the router. the Mac can
access the shared folder on the Dell, but the dell cannot find the Mac or the
printer.

Any ideas what I have to do the get XP to play nicely with others?
