SYMPTOMS

Server 4.0, your computer may stop responding (hang), and you may receive the
following error message:

  STOP C0000221 - Bad Image Checksum
  The image Oleaut32.dll is possibly corrupt the header checksum does not match
  the computed checksum.

Attempts to replace the damaged Oleaut.dll file using the Last Known Good
Configuration and the Emergency Repair Disk (ERD) are unsuccessful.

CAUSE
=====

The cause is unknown.

RESOLUTION
==========

To resolve this issue, replace the Oleaut32.dll file. Note that if you are
running Microsoft Internet Information Server 4.0, you may need to replace other
files as well.

If Windows NT Server 4.0 resides on a FAT (file allocation table) partition,
follow these steps:

1. Start the computer in MS-DOS.

2. Replace the Oleaut32.dll file in the %SystemRoot%\System32 folder with the
  Oleaut32.dll file included in Microsoft Windows NT 4.0 Service Pack 3 or
  later.

  NOTE: If you are performing this procedure on a Compaq computer, apply the
  latest Compaq Software Support Diskette (SSD).

3. Restart the computer.

If Windows NT Server 4.0 resides on an NTFS file system partition, follow these
steps:

1. Install a parallel installation of Windows NT Server 4.0, and then install
  the latest service pack for Windows NT 4.0 to the parallel installation.

2. Start the computer in the parallel installation.

3. Copy the Oleaut32.dll file from the parallel installation to the
  %SystemRoot%\System32 folder of the original installation.

  NOTE: If you are performing this procedure on a Compaq computer, apply the
  latest Compaq SSD.

4. Restart the computer to the original installation, and then remove the
  parallel installation.

If you replace the Oleaut32 file and your computer is running Internet
Information Server 4.0 on the original installation and the issue still occurs,
follow these steps:

1. Install a parallel installation of Windows NT Server 4.0.

2. Install the following programs on the parallel installation in the following
  order:

  a. Windows NT 4.0 Service Pack 3

  b. Microsoft Internet Explorer 4.0

  c. Microsoft Windows NT 4.0 Option Pack

  d. Microsoft Windows NT 4.0 Service Pack 4

3. Copy all files in the \Winnt\System32 folder, excluding subfolders, from the
  parallel installation to the \Winnt\System32 folder of the original
  installation.

4. Copy all files in the \Winnt\System32\Drivers folder, excluding subfolders,
  from the parallel installation to the \Winnt\System32\Drivers folder of the
  original installation.

5. Restart the computer to the original installation, and then, unless you
  receive a Dr. Watson error message, remove the parallel installation.

6. If you receive a Dr. Watson error message while you are starting the computer
  to the original installation, restart it to the parallel installation, and
  then follow these steps:

  a. In the original installation, rename the following files:

  Explorer.exe
  Comctl32.dll
  Kernel32.dll
  Ntdll.dll
  Shdocvw.dll
  Shell32.dll

  b. Replace the listed files with the same files from the parallel
     installation.

  c. Restart the computer to the original installation, and then remove the
     parallel installation.
