You may have noticed that if you use a Remote Desktop Connection (RDC) to connect to a Windows XP computer as the same user who is logged into the computer, the local user is logged out.
This behavior could be undesirable in some situations. Say you are trying to troubleshoot 4D Server running on a remote machine but you do not want to log the local user on that remote machine out while you are connected via RDC.
Microsoft refers to this "sharing" of desktops as session "shadowing".
Unfortunately it is not possible to shadow a Windows XP RDC session.
However, it is possible to workaround this limitation with Windows 2003 Server. Here are some articles you may find useful:
