Blue Screen Crash with stop code: 0x00000079


Applies to

NT4 SP4 Update

Problem

STOP error message:

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


Cause

After a Windows NT Server 4.0 Service Pack 4 upgrade, when rebooting the system, the ntoskrnl.exe file may have been replaced by the single processor version instead of the multi-processor version.   This may cause the above blue screen on some multiprocessor systems.

Solution

To correct this problem, do one of the following:
  1. Use the following KB article to modify your ERD diskette to replace the Single processor kernel with the Muliprocessor kernel.

-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.

  1. 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:
