Sometimes the best way to fix a problem is to have someone show you how. The Remote Assistance feature in Windows XP is a convenient way for an administrator to connect to your computer and walk you through the solution. After connecting to your computer, an administrator can view your screen and chat online with you about what you both see. With your permission, the administrator can use his or her mouse and keyboard to work with you on your computer.
