Crossover cable

[evanz]

what OS you got

best thing to get is a cheap router doesnt have to be connected to the internet

just connect both upto it through cat 5 cable (ethernet NOT cross over)

go into each computer and go through the network setup wizard (if xp)
create a few shared folder and you should "see" each other in the "my network places"

and make sure network sharing is on

if its win 7 they should by default detect each other

win 7 by default has a "public" folder which you can use to share in between
