WinNT 3.51 Service Packs (SPs) Incorrectly Update Newer SPs (154785)
The information in this article applies to:
- Microsoft Windows NT Workstation 3.51
- Microsoft Windows NT Server 3.51
This article was previously published under Q154785 SYMPTOMS
It is possible to replace a newer version of a Service Pack for Windows NT
3.51 with an older version. This is not intended behavior.
CAUSE
Version information was not updated for Service Packs 1, 2, 3 and 4 for
Windows NT 3.51. It is possible for any of these service packs to install
over a newer service pack.
RESOLUTION
Windows NT will now detect that a newer-version Service Pack is installed
and not install an older Service Pack over the newer version.
Note: If Service Pack 3 is installed over Service Pack 4, please
refer to the following article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed this to be a problem with Windows NT version 3.51
Service Packs 1, 2, 3, and 4. This problem was corrected in the latest
Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service
Pack, query on the following word in the Microsoft Knowledge Base (without
