KEYWORDS:kbenv kbsetup kbtool kbWinNT4sp6fix

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

 - Microsoft Windows NT Server version 4.0 
 - Microsoft Windows NT Workstation version 4.0 
 - Microsoft Windows NT Server, Enterprise Edition version 4.0

SYMPTOMS
========

When you upgrade a computer running Windows NT 4.0 Service Pack 3, 4, or 5 (SP3,
SP4, SP5), to Windows NT 4.0 Service Pack 6 (SP6), and the default time zone is
set to (GMT) Casablanca, Monrovia, the default time zone after the upgrade may
be changed to the (GMT) Greenwich Mean Time; Dublin, Edinburgh, London, Lisbon
time zone.

If your default time zone setting is (GMT) Greenwich Mean Time: Dublin,
Edinburgh, London, Lisbon, it may be changed to the (GMT) Casablanca, Monrovia
time zone.

CAUSE
=====

This behavior can occur because the Update.exe and Update.inf files cannot
differentiate between the two (GMT) time zones.
