System propertiesThe next thing you will need to do is to configure your desktop PCs to accept remote access connections. The steps are very similar for Windows XP SP 2, Vista Business, Vista Enterprise, or Vista Ultimate (the only operating systems supporting this feature).
First, you will need to allow Remote Access to your computer. On Vista this is done by right clicking on Computer and selecting Remote Settings. You will need to select the option "Allow connections from computers running any version of Remote Desktop (less secure)".
On Windows XP you will need to go the remote tab of system properties (accessible by right clicking on My Computer and going to properties), and select "Allow users to connect remotely to this computer". You will also need to select the users that have access. This is done by going to the Select Remote Users tab, and selecting the user that will have access.
