A: Check the registry values
======================
1. Click Start, Run and type Regedit.exe
2. Navigate to the following location
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services\ winmgmt
3. Double-click DependOnService and check if the Value data is RPCSS. If not, please change it to RPCSS
B: Reset the WMI repository
===================
1. Disable and stop the WMI service.
sc config winmgmt start= disabled
net stop winmgmt
2. Run the following commands.
Winmgmt /salvagerepository %windir%\System32\wbem
3. Re-enable the WMI service and then reboot the server to see how it goes.
sc config winmgmt start= auto
If the problem continues, let's try to re-register the WMI components
Re-registering the WMI
================
The .DLL and .EXE files used by WMI are located in %windir%\system32\wbem. You might need to re-register all the .DLL and .EXE files in this directory.
To re-register the WMI components, run the following commands at the command prompt:
cd /d %windir%\system32\wbem
for %i in (*.dll) do RegSvr32 -s %i
for %i in (*.exe) do %i /RegServer
Meanwhile, please check if the Svchost.exe process that has the WMI service crashes. If so, please refer to the KB982293 article to fix it.
