Or a password can be required to access the system remotely. When the Remote Desktop Preferences is set, the system can be accessed via Applications|Internet|Remote Desktop Viewer.  I was able to connect between my laptop and server, but there were issues seeing the refreshed screen.  I am not sure if it was that one machine was run gnome and the other was running kde.  There appears to be remote control.  But the results of the remote requests are not seen by the remote machine.  Perhaps this due to the router settings.  Anyway, good luck with this.
