How to Turn Off Remote Accessby Margaret Worthington
Remote access is a set of Windows XP features that let other people connect to your computer and control it. This overall feature is intended for troubleshooting, remote control and remote help sessions, but if you don't use it and you don't plan on using it, disabling remote access to your computer can help secure your computer against potential attackers.
Click on the "Start" button and right-click on "My Computer."
Click on the "Remote" tab after clicking on the "Properties" button.
Remove the check mark from the check box next to the label "Allow Remote Assistance invitations to be sent from this computer."
Remove the check mark from the check box next to the label "Allow users to connect remotely to this computer."
Click "OK" and the computer immediately turns off remote access to the machine.
