The information in this article applies to:

- Microsoft Windows NT Workstation version 4.0 
- Microsoft Windows NT Server version 4.0

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
reference the following Microsoft Knowledge Base articles:

If you are trying to restore the system to a bootable condition and remove
Service Pack 2, use the following steps:

1. If the partition is formatted as NTFS, install Windows NT to a different
  directory so the files on the partition are accessable.

2. If the partition is formatted as FAT, boot to MS-DOS.

3. Change directories to the Service Pack 2 uninstall directory:

  (%WinRoot%\$NtServicePackUninstall$)

  -or-

  ($NTSER~1 or similar name if under DOS)

4. Copy all the *.sys files in the uninstall directory to the
  %WinRoot%\System32\Drivers of the original Windows NT directory.

5. Copy Win32k.sys from the uninstall directory to%WinRoot%\System32.

6. Copy all other files to %WinRoot%\System32.

7. The system should now be starting correctly. Other errors may be encountered
  at this point, but the system should start.

8. 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.

9. 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.
