Err Msg: Driver Entry Point Not Found After Service Pack Upgrade

After you upgrade to any one of the Windows NT 3.51 Service Packs (1 to 5) and restart your computer, the following error message appears:

The following system events appear in the Event Viewer:

This problem occurs if the Service Pack UPDATE.EXE program does not copy the new NTOSKRNL.EXE file. When Windows NT 3.51 starts up after the Service Pack has been installed, the Service Pack SRV.SYS and the Windows NT 3.51 (Build 1057) NTOSKRNL.EXE are being used. These files do not work with each other.

To correct this problem, do one of the following:

• Run the Windows NT 3.51 Service Pack UPDATE.EXE again.
  
  -or-
• For a single processor system, copy the NTOSKRNL.EXE file from the Windows NT 3.51 Service Pack to the %SystemRoot%\SYSTEM32 directory.
• For a multi-processor system, copy and rename the NTKRNLMP.EXE (multi- processor kernel) file from the Windows NT 3.51 Service Pack to the %SystemRoot%\SYSTEM32 directory overwriting the NTOSKRNL.EXE.

NOTE: Some single processor RISC computers, for example, Sables, Demi- Sables, Gamma, and the Alpha 2100, use a multiprocessor HAL and should use the multiprocessor kernel.

Microsoft has confirmed this to be a problem in Windows NT version 3.51. 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 the spaces):
