Solution to Host not responding in SC VMM

I have been troubleshooting a WinRM related problem which was the main cause of an error shown in SC Virtual Machine Manager as “Host not responding”. The error always pointed to Win RM or Windows Management. I tried a lot of fixes, but nothing worked. Eventually I thought to rebuild the Windows Management repository. Here are the steps I took to fix this issue:

  1. Run this command on the errant server: net stop winmgmt (You will have to do this multiple times, or the step #2 will give you an error, file in use)
  2. rename the folder ‘Repository’ underneath %windir%\system32\wbem
  3. restart the system
  4. Done

The repository will be rebuilt automatically, OR you can rebuild it manually by running this command winmgmt /resetrepository (I did not have to do this)

PS: This also fixes the error in Server Manager which shows up under NIC teaming – “Host Unmanagable”
