We had earlier discussed using the WMI Diagnosis Utility in a post on Basic WMI Testing.  If you’re running this utility, you may found that the utility is reporting several missing core WMI files on Windows Vista and Windows Server 2008 systems and this is creating concern for the administrators.  When reviewing the log file of the WMIDiag.vbs output, they see entries such as the ones below:

..167 07:09:07 (1) !! ERROR: WMI System file 'C:\WINDOWS\SYSTEM32\WBEM\FRAMEDYN.DLL' is MISSING or is access DENIED.
..168 07:09:07 (2) !! WARNING: WMI System file 'C:\WINDOWS\SYSTEM32\WBEM\FRAMEDYNOS.DLL' is MISSING or is access DENIED but it is an OPTIONAL component.
..177 07:09:07 (1) !! ERROR: WMI System file 'C:\WINDOWS\SYSTEM32\WBEM\PROVTHRD.DLL' is MISSING or is access DENIED
..193 07:09:07 (1) !! ERROR: WMI System file 'C:\WINDOWS\SYSTEM32\WBEM\WBEMCOMN.DLL' is MISSING or is access DENIED.

Naturally, when running any sort of diagnostic report on a system, you would get concerned about the fact that core files are reported as missing.  However, in this particular instance, this is not a problem with the OS – but rather, an issue with the current version of the WMI Diagnosis Utility.  Several WMI core files, such as the ones listed above (FRAMEDYN.DLL, FRAMEDYNOS.DLL, PROVTHRD.DLL and WBEMCOMN.DLL) have been moved from the C:\WINDOWS\SYSTEM32\WBEM folder into the C:\WINDOWS\SYSTEM32 folder.  However, the WMIDiag utility hasn’t been updated to reflect that, which is why you’ll see these errors in the WMI Log.
