SYMPTOMS
After you apply Service Pack 2 for Windows NT 4.0 over the network and restart your computer, you may receive error messages stating that some files (for example Ntfs.sys or Advapi32.dll) are corrupt.



CAUSE
This problem occurs because the Service Pack 2 binary files were packaged using authentication for web distribution. You only experience this problem when you expand a previous version of Service Pack 2 and then copy the files from one computer with an NTFS partition to another computer over the network (and only when the two systems negotiate raw write mode between them.)

The specific files affected by this problem are:

  Ntfs.sys Advapi32.dll Winhlp32.exe Halapic.dll

This does not occur with the CD-ROM version of Service Pack 2.



RESOLUTION
The Service Pack 2 binary files were repackaged to resolve this problem. Please download the Service Pack 2 files again.

IMPORTANT: The files did not change, they were only repackaged without authentication.

NOTE: If your system no longer starts due to Ntoskrnl.exe or other critical system files being corrupt, you must replace these files manually. This may require you to install another copy of Windows NT in different folder so that you can access the original installation, especially on an NTFS partition.



MORE INFORMATION
If you experience this problem with the latest version of Service Pack, perform one of the following steps:
 * Copy the Service Pack locally and run Update.exe from your local hard disk.

-or-
 * Manually update the Rdr.sys file before you apply Service Pack 2 over the network. To do this, rename Rdr.sys in the %systemroot%\System32\Drivers folder, copy the expanded version of Rdr.sys from Service Pack 2 to this location, restart your computer, and then run Update.exe.
