Last reviewed: June 28, 1996
Article ID: Q150276

The information in this article applies to:

Microsoft Windows NT Workstation version 3.51
Microsoft Windows NT Server version 3.51

SYMPTOMS

When you install Windows NT 3.51 Service Pack (SP) 4 from the Microsoft ActiveX Developers Kit compact disc, the files NTbackup.dll and NTdll.dll are not copied correctly and the system stops responding.

When you run Update.exe for SP4, the following file copy errors are returned:

   An error has occurred.

   The file %systemroot%\system32\NTBACKUP.EXE was not copied correctly or
   is not a valid Windows NT Image.

and,

     An error has occurred.

     The file %systemroot%\system32\NTDLL.DLL was not copied correctly or
     is not a valid Windows NT Image.

Depending on what Hardware Abstraction Layer your system uses, you may also get a message such as the following:

   HAL: MPS MP structure not found
   HAL: No MPS Table Found

   HAL:  This HAL.DLL requires an MPS 1.1 system
   Replace HAL.DLL with the correct hal for this system

CAUSE

The file NTdll.dll, which is necessary to start Microsoft Windows NT, is corrupt. It is likely that both NTbackup.exe and NTdll.dll were not updated, and that both show the original Windows NT 3.51 dates.

RESOLUTION

Run the emergency repair process as documented in Chapter 2 of the Microsoft Windows NT Installation Guide. You will need to run the "Verify Windows NT system files" option to recreate the proper operating system file configuration. This process is also documented in the on-line help files on the NT 3.51 Workstation and Server compact discs under the \support\books subdirectory. You can also perform an upgrade install of Microsoft Windows NT to recreate a working operating system configuration. After you have a working installation of NT 3.51, run Windows NT 3.51 SP4. If your NT installation is on a FAT partition you can try to manually copy NTdll.dll from a working SP3.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
