Trying to setup Samba in Linux

[Scootin159]

Symptoms:
System not listed in workgroup for the domain.
When I type in \\10.2.31.199 into IE (the IP# of the linux box) or \\marge (it's name) it always just takes about 30 seconds to do anything, and then just shows a blank window

Anyone have any ideas on why this isn't working?
