Windows XP - How to add your computer to a workgroup

If your computer is already part of a network, you can join a certain workgroup so you can see all the computers on the network. To join a workgroup follow some simple steps:

Open Start Menu and right click on My Computer and choose Properties.

When the properties window appears, go to Computer Name tab and click on it. On this tab you can enter a computer description (optionally, if you want network users to easy recognize your computer). Click on Change to enter the workgroup name in your network (if you don't know it, just ask the network administrator for the workgroup name).

A new window will appear. Here you can enter your computer's name and then make sure Workgroup is checked and enter the workgroup name.Click OK and then restart your computer.

To see computers on the workgroup, open Network Places (from the Start Menu or open My Computer and click on My Network Places on the left panel), then click View Workgroup Computers on the Network Tasks  panel on the left.

If you want to see computers from other workgroups in your local network (if there are any), follow the step above and then click on Microsoft Windows Network from the Other Places panel on the left.
