On a Windows XP/Server 2003 machine system name can be changed as follows.
- Click Start Button
- Right click ‘My computer‘
- Select ‘Properties‘
- Select the tab ‘Computer name‘
Now you can see the computer name and also the name of the domain it is joined to if it is a XP professional or 2003 server box. We do not see domain name in XP Home machines.
- Now click on the button ‘change‘
Here we can reset the computer name and also join the computer to a different domain.
