How to Configure and Use Remote Desktop

Remote Desktop is designed to allow users to remotely gain access to a Windows XPProfessional desktop from another computer on the network. After connecting to theremote desktop, a user sees the remote desktop in a window and can access files, fold-ers, and applications on the remote computer. After a connection is established, thelocal desktop is locked for security reasons, preventing anyone from viewing the tasksthat are being performed remotely.Remote Desktop is designed to allow a user to have full control over a Windows XPProfessional desktop from another computer on the network or even from the Internet.This is useful when a user is working from home, another office, or another site andrequires access to information or programs on a primary office computer. While a useris remotely accessing a computer, local access by another user is not permitted. Anexception to this is an administrator; administrators are permitted to log on locallywhile another user is connected remotely, but the remote session is then terminated.When you are connected to a computer via Remote Desktop, many of the resources onthe host computer are available on the client computer. These resources include thefollowing:File System While you are connected to the remote host, the file system on the clientcomputer can be made available. If you open My Computer on the host computer,you will see the hard drives for the client computer. This feature allows you tocopy information between the host and client computer.Audio Audio generated on the host computer plays through the client computer’ssound system.
