The information in this article applies to:

- Microsoft Windows NT Server versions 4.0, 4.0 SP4, Terminal Server Edition 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you install Citrix Metaframe server-based software on your computer running
Windows NT 4.0, Terminal Server Edition, the computer may crash and either of
the following error messages may be displayed on a blue screen:

  

- STOP 0000000a : 39b880ce 00000002 00000000 801335d8
  IRQL_NOT_LESS_OR_EQUAL

- STOP 0000004e : 00000007 00000e32 00000001 00000000

NOTE: The parameters may be different, depending on your system configuration.

CAUSE
=====

In certain conditions, Metaframe's kernel mode driver (Cdm.sys) dereferences
physical pages that are not referenced. This creates a condition where the
reference count of a physical page is 0, but the share count is still 1 (the
page is still on some lists).

To preserve system integrity, Terminal Server Edition is set to crash when these
conditions are present.

RESOLUTION
==========

To resolve this issue, contact Citrix to obtain a fix for this problem. The
latest updates to the Metaframe Cdm.sys driver should also contain this fix.
