TITLE   :ERROR MESSAGE: Load Needed DLLs for HAL
PRODUCT :Microsoft Windows NT
PROD/VER:WinNT:4.0
OPER/SYS:
KEYWORDS:

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

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

SYMPTOMS
========

When you start your computer, you encounter the following error message:

   Load needed DLLs for HAL

CAUSE
=====

This error can be caused if you uninstall Diskeeper for Windows NT 3.5x after
you upgrade Windows NT 3.5x to Windows NT 4.0.

RESOLUTION
==========

If you install Windows NT on a FAT partition, start in MS-DOS mode and then
replace the affected files (Ntdll.dll, Ntoskrnl.exe, Fastfat.sys, and Ntfs.sys)
with the files from the Windows NT CD, or from the service pack, as applicable.

If you installed Windows NT on an NTFS partition, replace the files in one of the
following two ways:

1. Use the Windows NT 4.0 Emergency Repair Disk (ERD) for this system to repair
   the system files.

   WARNING: Ensure that you have a good backup of your system before using the
   ERD. Any services, applications, service packs, and so on, that you added
   after you created the ERD may be affected by using the ERD.

   - or -

2. Install Windows NT 4.0 into a separate directory. Start your computer with
   the temporary version of Windows NT 4.0. Replace the affected files
   (Ntdll.dll, Ntoskrnl.exe, Fastfat.sys, and Ntfs.sys) in the original
   installation with the correct version from the Windows NT 4.0 CD or the
   service pack, if you applied one. After you replace the files and start the
   computer without incident with the original version of Windows NT 4.0, it is
   safe to remove the temporary version of Windows NT 4.0.

MORE INFORMATION
================

When you install Diskeeper for Windows NT 3.51, it replaces the following files:
Ntdll.dll, Ntoskrnl.exe, Fastfat.sys, and Ntfs.sys. The original files are
renamed with an .org file extension. When you use the uninstall option in
Diskeeper, the original files are renamed, replacing the Diskeeper version of
these files. When you uninstall Diskeeper for Windows NT 3.51 after you install
Windows NT 4.0, the Windows 4.0 version of these files are replaced by the
Windows 3.51 version.

To prevent this problem, uninstall Diskeeper before installing Windows NT 4.0.

Executive Software has announced an updated version of Diskeeper for Windows NT
4.0. For additional information, please contact Executive Software.
