SYMPTOMS
On a multiprocessor system, after you apply the Windows NT 4.0 Post-SP2 (Service Pack 2) KRNL-FIX (Krnl40x.exe, where x is the processor type) the system will display a STOP error message:

STOP: 0x00000079 (0x00000002 0x00000002 0x00000000 0x00000000)



CAUSE
This error is a mismatched HAL STOP error message. It is caused by applying the single processor Ntoskrnl.exe, rather than using the Ntkrnlmp.exe file, which needs to be renamed to Ntoskrnl.exe before the fix is applied.

The README file from the fix includes this information:

Note: If the target computer is a multiprocessor system, then perform the following command in order to replace the uniprocessor version of the kernel with the multiprocessor version. This step must not be done if the target computer is a uniprocessor system.

Copy NTKRNLMP.EXE NTOSKRNL.EXE

To install this hotfix, put the new Ntoskrnl.exe, hotfix.exe, and hotfix.ini in the same (temporary) directory, and then type:

hotfix /install

After installation, type hotfix to verify that it was installed correctly, then perform a reboot the system.



RESOLUTION
To correct this problem, do one of the following:  If Windows NT is installed on a FAT partition, replace Ntoskrnl.exe in the %SystemRoot%\System32 directory with the Ntkrnlmp.exe from the Post-SP2 KRNL-FIX. In the %SystemRoot%\System32 directory, rename Ntkrnlmp.exe to Ntoskrnl.exe.

Reboot the computer and restart Windows NT.

-OR-

 If Windows NT is installed on an NTFS partition, re-install Windows NT to a separate directory (parallel installation). Boot into this new installation. Go to the original Windows NT %SystemRoot%\System32 directory and replace Ntoskrnl.exe with the Ntkrnlmp.exe from the Post- SP2 KRNL-FIX. In the %SystemRoot%\System32 directory, rename Ntkrnlmp.exe to Ntoskrnl.exe.

Reboot the computer and restart Windows NT, starting into the original version of Windows NT. If the original version now starts properly, the "parallel installation" can be deleted. This can be done using Explorer, File Manager or My Computer.

WARNING: Use caution when deleting operating system subdirectories or modifying the Boot.ini.

Delete ONLY the Windows NT directory that was created for the parallel installation; do NOT delete the original installation.

In addition, the Boot.ini can be modified to remove references to this now non-existent version of Windows NT. If the parallel installation was installed to a directory called Winnt.bak, delete only those lines in Boot.ini that have Winnt.bak. Also, make sure that the "DEFAULT=" entry is directed back to the ARC path and directory for the original installation of Windows NT.

For additional information on the Boot.ini file, please see the following article in the Microsoft Knowledge Base:
