I have a non-virtual Windows 2003 Server SP2 with McAfee Solidcore installed. A few days ago I noticed that for over a few months, once every constant amount of time, around 24 hours, a bunch of Solidcore application errors appear in the event viewer. The events read as follows:

"McAfee Solidifier prevented an attempt to modify file "C:\windows\system32\msyuv.dll" by process C:\WINDOWS\system32\wbem\wmiprvse.exe (Process ID: 1234, User: NT AUTHORITY\SYSTEM)

This also happens for the following files, in every batch of errors: windows\system32\msvidc32.dll windows\system32\msrle32.dll windows\system32\iyuv_32.dll windows\system32\msh263.drv windows\system32\tssoft32.acm windows\system32\msgsm23.acm windows\system32\msg711.acm windows\system32\msadp32.acm windows\system32\imaadp32.acm

And more.

Google searches and crawling MSDN and other Microsoft knowledge resources have turned up nothing useful regarding the cause for this behavior. Unfortunately, I can't reproduce the issue and it has not happened for several weeks now, so it's not possible to look into it in real time.

This also occurs on several different servers, some on the same LAN and some on a completely different network. All of them are Windows Server 2003 SP2 and non-virtual.

Any help would be appreciated.
