Easiest and cheapest way is to get two PCI ethernet network cards and a cross-over cable.
You can buy "starter network kits" which consist of the above.
Otherwise you have to make your own cables.
If you decide to make your own, you want 10/100 or 10 base 100 cards and 10/100 CAT 5 UTP cable, and a couple of RJ45 cable ends.
The cable <b>must</b> be a cross-over if you want either computer to send <b>and</b> receive data from the other.
Install the network cards as you would normally install PCI cards. Once installed and the software is installed, you need to configure each computer to 'see' the other.
Go to "Control Panel/Network" and ensure the TCP/IP protocol is present in the list of netwrok components. Next go to the file & print sharing tab, and click both the sharing boxes to allow others access to the system.
Next, go to the "Identification tab, and ensure that each computer has a name, and that the workgroup for each computer is identical.
Apply all changes for each system and shut down. Connect with the cross-over cable and start em up!
You will probably be prompted for network passwords (its been a while since I last did this), and throw in what you want to.
Go to neighbourhood network, and hopefully you'll see the other computer there. If not, press F5 every few seconds or so, as it sometimes takes time to get going.
Lastly. I can't remember which setting is supposed to be used here, so forgive me. Back in the Control Panel/network there was a primary Logon tab. I can't honestly remember which one you use. Try either.
Sorry I can't be more helpful.
