A Remote Desktop session is disconnected without warning if a session reconnect request does not complete as expected on a Windows Server 2003-based computer (843301)

CAUSE

This problem may occur if the Citrix ICA Client tries to reconnect to the Citrix MetaFrame Presentation Server by using a different color depth than the color depth that was used during the original session. For example, if you follow these steps, the session is disconnected:

You use the Citrix ICA Client to connect to the Citrix MetaFrame Presentation Server, and you use the High Color (16 bit) color depth.
You disconnect from the session.
You change the color depth to 256 Colors.
You try to reconnect to the same Citrix MetaFrame Presentation Server session as the same user.

When you follow these steps, the Citrix session does not reconnect. Because the Citrix session does not reconnect, the Remote Desktop session is disconnected without warning.
