Connect a computer to a server setting up the computer as a client of the server. You need a network interface card, an Ethernet cable and a network router.
Start by putting the network interface card in the computer. Most network interface cards use the PCI port to connect to the motherboard. To identify a PCI port, look for long ports under the CPU. Once the card is in place, plug one end of the Ethernet cable to the card and the other to any vacant port on the router. Wait for the connection indicator on the router to light up.
Launch the Control Panel, click Performance And Maintenance, and then click System. Navigate to the Computer Name tab, and indicate names for the computer and the workgroup. The computer and the server must have the same workgroup name.
Open the Control Panel again, click Network Connections, right click on Local Area Connection, select Internet Protocol, and click Properties. Pick an IP address for the computer. Make sure to pick an IP address that only differs from that of the server in the final digit.
Restart the server, the router and the computer to activate the connection. If unsure about the IP address of the server, open the Command Prompt, and use the "ipconfig /all" command.
