Unattended Encryption Setup Problem Adds Event Log Entry in SP6

ID: Q240299

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 install the 56-bit version of Windows NT 4.0 Service Pack 6 (SP6) on a computer that already has 128-bit security installed, the following error message appears:

Service Pack Setup Error

You have chosen to install a version of the Service Pack with Standard Encryption onto a system with High Encryption. This is not supported.

To successfully install this version of the Service Pack, you must install the High Encryption version. Press Help for more information about obtaining the High Encryption Version of this Service Pack.

Service Pack Setup will now exit.

When you click OK, the service pack installation process is stopped. However, if you are performing an unattended installation, an error message is not displayed. Instead, an error message is written to the Event Viewer System log as follows:

Windows NT Service Pack 6 installation failed.

Installation of the Standard Encryption version was attempted on a system with High Encryption.

CAUSE

This behavior occurs because some programs (for example, Microsoft Systems Management Server) do not support an error message dialog box during unattended installations.

STATUS

This behavior is by design.

MORE INFORMATION

Administrators (or users) need to be aware of the absence of a dialog box in unattended installations of SP6 and consistently check event log entries after performing unattended installations.
