How to Fix Windows XP Using a Different Computer

1. Verify that the host computer is running Windows XP Professional, as Windows XP Home does not support Remote Desktop. The remote computer must be running Windows 95 or higher.
2. Sign in as the administrator on the host computer.
3. Click on the 'Start' menu. Select 'Control Panel' from the right side of the menu. Choose the 'Performance and Maintenance' option.

5. Select 'Firewall' in the 'Control Panel' menu. Select 'Windows Firewall' at the bottom of the screen. Verify the 'Don't allow exceptions' is unchecked. Select 'Exceptions' tab and click on the box labeled 'Remote Desktop.' Click on 'OK.'
6. Select the 'Performance and Maintenance' in the 'Control Panel' screen. Select 'System' and click on the 'Computer Name' tab. This will be the name you use to remotely connect to this PC.
