If all you wish to do is connect two computers using standard NICs', then you need a crossover Ethernet cable. A crossover cable is different from a strait patch cable in that pin pairs 1 and 3 (total 4 pairs or 8 wires for Category 5) are crossed on one end of the cable. You may not be able to readily buy a crossover cable at a computer store, but making your own is fairly simple and easy with the right tools. All you need is a crimp tool, a few RJ-45 connectors, and a piece of Cat5 cabling. Search techrepublic for instructions on making crossover cables. There is a good section on it.

2 x rj 45, cable cat 5 utp, crimp tool
You can make the connexion like this
connector A:white-orange,orange,w-green, blue,w-blue,green,w-brown,brown
connector B:w-green,green,w-orange,blue,
w-blue,orange,w-brown,brown.
or you can make it like this wire no.1 from the first end of the cable goes to position no 3 (second end of the cable) wire no.2 goes to 6 , wire no 3 goes to 1, wire no 6 goes to 2.(others does not matter).Look down

if you have an older nic you can use thinnet, 2 bnc t pieces and 2 terminators for a cheap quick network that you can expand if you have to connect another machine
