What does this error mean and what do I need to do to resolve it?

Is this happening on one computer or multiple computers?

1. About how to rebuild the WMI repository.

• Disable and stop the winmgmt service
• Remove or rename C:\Windows\System32\wbem\repository
• Enable and start the winmgmt service
• Open Command Prompt as Administrator
• Run the following commands:
cd C:\Windows\System32\wbem\
for /f %s in ('dir /b *.mof') do mofcomp %s
NOTE: This will take a minute or so to complete.
for /f %s in ('dir /b en-us\*.mfl') do mofcomp en-us\%s

Hope this helps,

Although this has been about 2 years, I wanted to come in and say that this (or a version of this) worked for me. 

I was unable to load ANYTHING into Vault using Autoloader, until I created a .bat file with this content:

@echo off
sc config winmgmt start= disabled
net stop winmgmt /y
%systemdrive%
cd %windir%\system32\wbem
for /f %%s in ('dir /b *.dll') do regsvr32 /s %%s
wmiprvse /regserver
winmgmt /regserver
sc config winmgmt start= auto
net start winmgmt
for /f %%s in ('dir /s /b *.mof *.mfl') do mofcomp %%s

For those that are unsure. Create a .txt file, add this text in, make sure you have file extensions shown in windows, and change the .txt to .bat
Next you'll need to run this .bat file as administrator. If you don't want to do that, simply run your command prompt (cmd) as admin, and enter this text.
Restart your machine, and you should be good to go!

Thanks!
