How to Change Computer Name

and Join a Workgroup in Windows XP

Fix any Windows Error and optimize your System!

When you change computer name and join a workgroup it will get you closer to setting up your home or small office network.

computer name identifies your computer on the network.

Each computer on your network must have a unique name in order to communicate in the network. If two computers have the same name, it creates a conflict for network communications. Microsoft suggests that you keep your computer name short and simple.

workgroup is also called a peer-to-peer network.

If you have fewer than ten computers in your home or small office network then it is recommended to configure your computers with the same workgroup. This will allow your computers to communicate and share resources with each other. If you have more than 10 computers on your network then it is recommended to use a server instead of a workgroup.

A workgroup will allow you to:

  • Share your files. (audio, videos, pictures and documents)
  • Share a printer from all computers on the network.
  • Access any file from any computer.
  • Share the Internet connection using Internet Connection Sharing (ICS).

Let's configure your computer name and join the computer to a workgroup. The easiest way to accomplish this would be to run the Network Setup Wizard. The Network Setup Wizard will guide you through the steps needed to set up your home or small office network.

This tutorial will show you how to basically do the same setup that Network Setup Wizard does.
