Default (GMT) Time Zone Changes During Service Pack Upgrades

ID: Q241331

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.

STATUS

Microsoft has confirmed this to be a problem in Windows NT 4.0.
