If your computer is running Windows XP you can use a feature called Remote Assistance that would let me take control of your computer over the Internet to fix a problem on your PC!

We use it at work. The technician is sitting in a different city, but he is moving my cursor and typing characters just like he was sitting in front of my PC. It is neat to watch it work. Like a ghost is running it.

If you are running Windows XP and ever need my help (printer settings, network connections, Word, Excel, Access, etc.), let me know and I would be glad to log-in to your computer and fix you up.

This is what the introductory help screen in Windows says about it:

Providing help using Remote Assistance
Sometimes the best way to help someone fix a problem is to demonstrate a solution. If you are invited, Remote Assistance is a convenient way for you to connect to a friend's computer from your computer running a compatible operating system, such as Microsoft Windows XP, in order to walk your friend through a solution.

After you are connected, you will be able to view your friend's computer screen and chat together in real time about what you both see. With your friend's permission, you can even use your mouse and keyboard to work with your friend on his or her computer.

Notes
• You and the person you are helping need to be connected to the Internet while using Remote Assistance.

• If you are working on a local area network, firewalls might stop you from using Remote Assistance. If you have not sent your invitation by using Windows Messenger, try that. If that doesn't work, ask your assistant or administrator to add port 3398 for you.

• You might want to let the person you're helping know that they can improve performance by using the Color Quality setting in Display options (in Control Panel) to reduce the number of colors his or her screen displays.

• To improve viewing, you can click the Actual Size or Scaled buttons. Viewing in scaled size shows more of the other user's screen but in a reduced view. Viewing in actual size shows less of the screen but in real size.
