Login to you computer using the administrator account and then click the ‘Start’ button. Keep in mind that remote access cannot be enabled using an account with limited rights, so it is important that you login with the administrator account.
In the ‘Start’ menu, right click the ‘My Computer’ icon and then click ‘Properties’.
This will open a dialogue box labelled ‘Properties’ with multiple tabs. Look for the tab labelled ‘Remote’ and click it. Under this tab, check the option labelled ‘Allow users to connect remotely to this computer’.
Windows XP will prompt you to confirm the change you just made. Do so by clicking the OK button.
If you would like to remotely access this computer using an account other than the administrator account, you will need to click the button captioned ‘Select Remote Users’. Then click the ‘Add’ button and list all the users whom you would want to grant remote access. Make sure that the accounts you add are real and exist on your computer.
Click the OK button for the changes you just made to take effect. Remote access is now enabled on your computer. However, if your computer is behind a router and you would like to access it via internet, you will have to forward the 3389 port to the computer. This can be done using the router’s web interface. On information on how to access the router’s web interface, read the instructions manual that came with the router.
