-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server versions 4.0, 4.0 SP6, Terminal Server Edition 
-------------------------------------------------------------------------------

SYMPTOMS
========

A shadowed client session that is running an MS-DOS-based program has keyboard
problems after you quit shadowing by pressing the CTRL, ALT, or SHIFT keys.

CAUSE
=====

This problem can occur because when shadowing stops, the server does not reset
any residual shift states that may occur from the use of shadow keys.


RESOLUTION
==========

A supported fix is now available from Microsoft, but it is only intended to
correct the problem described in this article and should be applied only to
systems experiencing this specific problem. This fix may receive additional
testing at a later time, to further ensure product quality. Therefore, if you
are not severely affected by this problem, Microsoft recommends that you wait
for the next Windows NT 4.0 service pack that contains this fix.
