SYMPTOMS
When a Terminal Server client reconnects to a Microsoft Windows 2000-based Terminal Server session, you may receive the following Stop error message:

STOP 0x00000050 (PAGE_FAULT_IN_NONPAGED_AREA)



CAUSE
Typically, this problem occurs when the following events occur:
 * 1) The Terminal Server client connects to a Terminal Server session that is running in 24-bit color.
 * 2) The Terminal Server client disconnects from the Terminal Server session.
 * 3) The Terminal Server session switches to 8-bit color.
 * 4) The Terminal Server client tries to reconnect to the Terminal Server session.

This problem occurs because the Terminal Server stores the wrong color data size for the disconnected session. When a Terminal Server client reconnects to a session that is using a lower color depth than the original session, the Remote Desktop Protocol (RDP) display driver uses the originally cached color depth. Therefore, you receive the error message that is described in the &quot;Symptoms&quot; section.
