DOCUMENT:Q249135 10-AUG-2001 [winnt] TITLE :Cannot Apply 56-Bit SP6/6a to 128-Bit Windows NT 4.0 PRODUCT :Microsoft Windows NT PROD/VER:winnt:4.0 OPER/SYS: KEYWORDS:kberrmsg ====================================================================== ------------------------------------------------------------------------------- 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 ------------------------------------------------------------------------------- SUMMARY ======= You cannot apply the 56-bit (standard encryption) version of Service Pack 6 or 6a to a version of Windows NT 4.0 that is running a 128-bit (high encryption) version of a service pack. MORE INFORMATION ================ If you attempt to apply the 56-bit (standard encryption) version of Service Pack 6 or 6a to a version of Windows NT 4.0 that is running a 128-bit (high encryption) version of a service pack, you receive the following error message: 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. In earlier service packs, installing a lower-encryption service pack generates an error message stating that you are about to downgrade the level of security, but you can install standard encryption over high encryption. In Service Pack 6/6a, you cannot do so.
