I had an issue recently with some Hyper-V servers where it was noticed that the Hyper-V system services (VMMS, VHDSVC & NVSPWMI) gets stopped all in a sudden and no one can access or manage the Hyper-V Virtual machines from the console as per attached image.

I noticed that these services stop on specific time on daily basis, after several investigations it was related to a specific rule/job based on WMI (CCMEVAL) that runs from the System Center Configuration Manager 2012 (SCCM) server

The only thing related to WMI that was updated on December is the Windows Management Framework 3.0 (KB2506143)


When this update get installed the SCCM client health check Read/Write WMI actions fail resulting in these services stopped.

To fix this issue Uninstall this KB and reboot the server, If this didn’t work, please try the following:

  1. Uninstall the Windows Management Framework 3.0 (KB2506143)
  2. Run ccmclean.exe /all to uninstall the ConfigMgr 2012 client.
  3. Run ccmdelcert.exe
  4. Once the above steps are done, rename the WMI repository and restart the WMI service
  5. Reboot the Server
  6. Install the ConfigMgr 2012 client and check the services.

Microsoft released a bulletin confirming this KB compatibility problems with SCCM 2012


This issue will get fixed with SCCM2012 SP1 expected to be released Quarter 1 2013.
