If you don't need to have internet access then use Net Beui, other wise install TCP/IP protocol.
1. Install a NIC card per puters.
2. Boot puters and follow wizard walk through to install the NIC divers and apropriate protocols.
3. Both puters have to have unique name and in the same workgroup (If use TCI/IP then both puters need to config same Subnet Mask, but each with unique IP address)
4. Under Control Panel > Network, install and enable Printer and File Sharing for MS Network.
5. Right click: drive, folder, or printer to share that particular resource.
* Note, to config Workgroup & Puter name, goto: Control Panel > Network > Identification.
** Config, TCP/IP, goto: Control Panel > Network > TCP/IP -> Dialup Adapter > IP Address > Specify an IP Address. (could use the address that your IP service provider give to you...Log on to the internet service and type WINIPCFG at Dos Promt to get the static IP & Gateway. Also could use the Default Subnet provided if you want, but you could just make up your own)
