text: If you have Windows XP Professional (ONLY!) or Windows Server 2003, you can right-click on My Computer and go to properties.  Under the Remote tab if you check the box "Allow users to remotely connect to this computer" then you will be able to connect using Start -> All Programs -> Accessories -> Communications -> Remote Desktop.  You will only be able to connect with users that are Administrators of the computer or users that you specify by clicking "Select Remote Users...".  Note that Windows XP Pro only allows one user to be active at once no matter what.  If you want to make a real terminal server using Windows Server, you will have to purchase additional terminal server licenses from Microsoft and then install them on your server.
