Peer-2-Peer

Both computers must have a network adapted installed. Connect a cross-over cable between the two computers. Go to Control Panel and setup an ip address of 192.168.1.1 with a subnet mask of 255.255.255.0 on one computer in the TCP/IP properties of your Network Adapter. Install Microsoft's NetBEUI protocol.

On the second computer do the same, but the ip address will be 192.168.1.2 and subnet will be 255.255.255.0

Both computers should have "File and Printer Sharing Enabled". and sharing of files checked.

reboot and login. Using Windows Explorer, you should be able to right-click on a folder and set a share on it from either computer.

Another alternative is to connect both computers to a hub and setup your P2P(peer-to-peer) with regular cables (which allows you to add computers at a later time if you like).

Use the following Ref for peer-to-peer setup

Install a NIC in each PC and configure, Netbeui does not need any configuration, but you should give each computer a name and set them all for the same workgroup, also file and print shareing. Then connect each computer to a hub. At this point youhave a basic peer to peer network each computer should be able to see the others by browsing and any resources offered.

If you gave some more information about what you wanted to do and how many computers.

1 - power down and install NIC
2 - power up install drivers, reboot
3 - Control Panel Networking 3 tabs
4 - add File and Print sharing, remove any un-needed protocols
5 - Identification, assign a computer name and workgroup (same workgroup for all PCs)
6 - security should be share level
7 - connect each computer to a hub
8 - Network Neighborhood, slight delay until all computers show here but the P-2-P is up and running.
9 - set any shares, folders/printers from computers
10 - test to make sure you can access shares
11 - take a break and plan for the next upgrade to the network
