Upgrade Installation of Windows NT 4.0 Results In STOP Errors (166828)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q166828 SYMPTOMS
After you install Windows NT 4.0 as an upgrade over an existing
installation of Windows NT 4.0 that had a service pack installed, one or
more of the following errors may occur:
STOP: 0x0000001E (0xC0000005, 0xFF1BBD79, 0x00000000, 0x00000038)
KMODE_EXCEPTION_NOT_HANDLED Address ff1bbd79 has base at ff1ae000 -
tcpip.sys.
-or-
STOP 0x00000050 (0xFF10c004, 0x00000000, 0x00000000, 0x00000000)
PAGE_FAULT_IN_NONPAGED_AREA
NOTE: The first argument may change but the STOP code (0x00000050) is the
same. This may occur either as an in-place upgrade of Windows NT or as an
upgrade of Windows NT Workstation to Windows NT Server.
CAUSE
Windows NT 4.0 was reinstalled as an upgrade over an installation of
Windows NT 4.0 that had Service Pack 2 or greater installed and Remote
Access Service (RAS) was installed.
RESOLUTION
For more information on these specific errors and their resolutions, please

If you are trying to restore the system to a bootable condition and remove
Service Pack 2, use the following steps:
- If the partition is formatted as NTFS, install Windows NT to a different
directory so the files on the partition are accessable.
- If the partition is formatted as FAT, boot to MS-DOS.
- Change directories to the Service Pack 2 uninstall directory:
(%WinRoot%\$NtServicePackUninstall$)
-or-
($NTSER~1 or similar name if under DOS)
- Copy all the *.sys files in the uninstall directory to the
%WinRoot%\System32\Drivers of the original Windows NT directory.
- Copy Win32k.sys from the uninstall directory to%WinRoot%\System32.
- Copy all other files to %WinRoot%\System32.
- The system should now be starting correctly. Other errors may be
encountered at this point, but the system should start.
- Start the Service Pack 2 update program but select to uninstall the
service pack. This should bring your system back to a PRE-SP2
configuration.
- If the service pack was not the source of your original problem,
Microsoft suggests you re-apply the service pack, but choose NOT
to make an uninstall directory in order to preserve your original
Windows NT system files already contained in the previous uninstall
directory.
STATUS
Installing Windows NT 4.0 as an upgrade over an installation of the same
version is not recommended or supported. If files need to be replaced, boot
to MS-DOS if using a partition formatted as FAT and replace the damaged
files, or perform a new installation of Windows NT to a different directory
so a partition formatted as NTFS can be accessed and then replace the
affected files.
An upgrade will attempt to replace files and modify the registry. This may
result in mismatched files and/or corruption to the registry that may leave
the system unbootable. The in-place upgrade does not replace all service
pack files, thus creating an incompatible mix of service pack and non-
service pack system files.
MORE INFORMATION
This process will NOT work if Service Pack 2 was installed more than once
and the uninstall option was selected without first uninstalling the
service pack, thus overwriting the uninstall directory. Nor will this work
if the uninstall option was not selected during install of the Service
Pack. In this case, a parallel install of Windows NT will be needed so a
tape backup of the original install can be restored.
