   Thank you, that saved me a lot of time. I was about to re-install the whole machine to be sure that everything works fine. I assume that the error occured because I installed HPE Management Software which depends on WMI right after I installed the Hyper-V role. I wasn’t aware that this destroys the whole system ;o)

   Best regards
   Dave :o)

   Just had the issue today. Did a google search and your article came up on top. Lucky me. This fixed it. Thank you.

10. Martijn Daas on July 16, 2018 at 21:58

    Thank you!
    As somebody mentioned here also, it has something to do with installing HPE System Management Homepage after installing Hyper-V.
    Nice find, thumbs up.

11. Ceraz24 on July 21, 2018 at 16:11

    I can confirm this fixed it for me as well. I had the Homepage already installed but only when I installed the WBEM Provider Packager – cp031735 the error occured (for me at least)

    Cheers

    before doing this, use your domain administrator credentials if you have one if not use this command.

    Thanks for this article, it fixed the issues I was having with HyperV manager and HyperV 2016 core server.

18. Jeff on October 10, 2018 at 20:39

    Worked perfectly! Thanks for posting!

19. JonR on October 27, 2018 at 17:57

    Wow. Thank you for this simple and effective article. Also happened after HPE software install.

20. Jason H on November 14, 2018 at 01:28

    This fixed it! Thanks! Issue occurred on 11/13/2018 spontaneously on a computer I use Hyper-V on extensively. I literally had several VMs already open, left for a meeting, and came back to this error. Rebooting did not solve it. This did.

21. a.t on March 6, 2019 at 15:26

    thanks a lot, worked like a charm. i appreciate you saving the hair on my head.

22. Kevin A on March 28, 2019 at 21:36

    The suggested command did not work for me. For those who fall into this category, I resolved by opening Powershell on the host and typing > enable-psremoting -force. This will make the appropriate exceptions in your client firewall.

23. Stephen on May 28, 2019 at 16:40

    Great Solution! Many Thanks. I had the issue when the drive hosting my VM’s failed. I replaced the drive, but couldn’t subsequently connect to the Hypervisor.

24. bo on July 4, 2019 at 09:22

    File ‘C:\Windows\System32\WindowsVirtualization.V2.mof’ not found!

    How to Solve the Problem？

25. jacob on August 19, 2019 at 19:18

    also, i found that i had set a static entry in a hosts file but the hv-server was setup on dhcp; so assigning it the correct static ip address worked as I was trying to connect to the wrong system

26. Nithin on September 3, 2019 at 22:04

    This fixed my issue too. Thanks!

27. Emil on September 18, 2019 at 13:38

    Worked for me perfectly. God bless save me sleepless nights. Thanks you !

28. Rod on October 15, 2019 at 17:48

    You save my time thank you

29. miro on October 26, 2019 at 03:01

    OMG, why does Microsoft not do something and write up a knowledge based article that links to this website since so many people, including me, have experienced this ongoing issue. Server is 2019 and the issue is still present 2 years running!

30. Anonymous on December 17, 2019 at 21:47

    thanks was looking for this for past 8 hours.

31. Speedy on March 27, 2020 at 08:31

    Thanks!

32. Mike D on April 15, 2020 at 23:36

    Worked perfectly. Good find and thanks for posting it.

33. Patrick K. on April 22, 2020 at 07:40

    Searched for hours for a solution. Your command line did the job in seconds. Thanks a lot.

34. Jamie on May 14, 2020 at 16:57

    Thanks, This seemed to happen once I installed the HPE Proliant Support Pack….

35. Gary R on July 16, 2020 at 12:51

    Absolute star!
    I can confirm this fixed it for me as well. I had the Homepage already installed but seemed to break HV when I installed the WBEM Provider Package – cp037689 on Server 2019

36. Antec on November 17, 2020 at 19:06

    Thank you! worked perfect! Server 2016

37. Nathan Ashe on November 17, 2020 at 23:25

    I’ve found this solution many times, however non of them state if you run that command on the Server your trying to connect FROM or the server your trying to connect TO.

    I have just done it on both, without any luck.

38. Anthony Feghaly on November 26, 2020 at 22:31

    It worked for me perfectly, Thank you

39. Simon on March 14, 2021 at 23:23
