Windows Vista is a version of the Microsoft Windows operating system, preceded by Windows XP. If you want to be able to communicate from a Vista computer to an XP computer remotely, you can do so using the Remote Desktop Connection utility that is installed on both Vista and XP.
Go to the computer that has XP Professional installed on it, right-click "My Computer", select "Properties" and then click on the "Remote" tab.
Check the box marked "Allow users to connect remotely to this computer" and then click the "OK" button.
Go to your Windows Vista computer, click the "Start" button, type "mstsc" and then click on the "mstsc.exe" program that appears.
Type in the name or IP address of your Windows XP computer and hit the "Connect" button. You are immediately connected to the computer, and you are requested to provide a username and password to login. Once you enter this information, you may remotely control the computer.
