on Windows 2000/XP

In order to configure each computer, you need only go to the control panel, then double-click on “network connections“, and then right/click “local network connection“, and select properties!

The various protocols installed are shown in the local network connection window. In order to be able to share your files, play games on the network, and use your printers, it is necessary to install the following protocols:

  • Microsoft network client
  • File and printer sharing for Microsoft networks
  • QoS packet planner
  • Netbios Nwlink
  • NWLink IPX/SPX/NetBIOS-compatible transport protocol (for old games)
  • TCP/IP Internet protocol

If one of these protocols is absent, click on “Install…” and add it.

Each computer must then be assigned an address, called an IP address in order to be able to communicate. In order to do this, you have to select “Internet protocol TCP/IP” and click on “Properties“.

The assignment of IP addresses may be done automatically or be manually defined, which is preferable for a small LAN. We will commonly assign these addresses:

Computer no. 1
IP address:
Subnet mask:
Computer no. 2
IP address:
Subnet mask:
Compuer no. xxx
IP address:
Subnet mask:

Once the IP address is allocated, you just have to close the window by clicking on OK (the DNS (domain name servers) will be left on automatic)

For optimal functioning, it is useful to check whether the network computers are part of the same workgroup. To do this, just right-click the workspace and select “properties“. Under the tab “Computer name” you will see the name of the computer as well as the workgroup to which it belongs. In order to modify the work group and do the same for all computers, you just have to click on”Network ID “;

The next step is to make sure that all of the computers communicate well together.
At the command prompt (MS-DOS command window by opening Run menu and typing “cmd“): With PC no. 1, type the following command, which allows you to verify whether PC no. 1 can see no. 2.


Then, try the following command, which allows you to verify whether the name given to a computer corresponds to the right IP address:

ping ComputerName

… and so on with the various computers on the network.

The command below allows you to see the network configuration details of the computer, in particular to see the running machine’s IP address if it was automatically assigned:

ipconfig /all
