A few days after a new Win2K OS install, I am finding numerous logs in the System event viewer that read:

Windows File Protection
File replacement was attempted on the protected system file c:\winnt\system32\XXXXXX. This file was restored to the original version to maintain system stability. The file version of the bad file is, the version of the system file is

No one was working on nor logged into the server during the times of these logs.

What would cause windows to activate the FPS on such files?

SQL Server 2000 was installed, no drivers were installed.

As of this morning there are more events in the log. They keep occurring while no one is using the box!

Some of files I see getting restored are:

that is very odd.  those file as yo kow are only for the creation of terminal server client disks.

go to and run housecall a free AV scanner.

I did not think that FPS would cover those files.

A work around would be to copy the file to your desk top and then re boot into safe mode.  once in copy the file over top of the regular files.  FPS is shut down in safe mode so it should break the cycle and there will be no back up files to restore.

that should stop the errors but may not be the correct solution.

Housecall found malware.PE_Parite.A, it had infected hundreds of files. I have no idea how the trojan got on the system, since it's a 3 day old clean install. I will see if this clears up the FPS issues.

I am running service pack 4

The virus seems to have been causing the FPS errors.
