environment: windows server 2022

error description: "An error occurred while attempting to connect to server <host>. Check that the Virtual Machine Management service is running and that you are authorized to connect to the server.

Hyper-V encountered an error trying to access an object on computer <host> because the object was not found. The object might have been deleted. Verify that the Virtual Machine Management service on the computer is running."

I have tried the "MOFCOMP %SYSTEMROOT%\System32\WindowsVirtualization.V2.mof" and some other possible solutions but they didn't work

cause: after the internect interrupt and reconnect, the error happened, I have also found no vmms runs.

Did anyone face the same problem? Any possible solutions?

    I had this exact same problem on my personal computer at home tried 5 different complex solutions and then solved it very easily with these 5 steps.

    1.) open windows security

    2.) click app and browser control

    3.) click exploit protection settings

    4.) in the system settings tab find "control flow guard" and set it to "on by default"

    5.) then restart, once you're back on your desktop and open hyper v manager it should automatically detect your local system

    This worked for me hopefully it works for you as well cheers.

    Hi BSD2,

    Hope you're doing well.

    Please follow the following steps to check this issue:

    1. Double-check that the Hyper-V Virtual Machine Management service (vmms) is running on the server. You can do this by opening the Services application (services.msc) and ensuring that "Hyper-V Virtual Machine Management" is running.
    2. It's possible that the virtual machine (VM) configuration files are corrupted or missing. Navigate to the location where your virtual machines are stored (default is usually "C:\ProgramData\Microsoft\Windows\Hyper-V") and check if the VM configuration files are present. If they are missing, you might need to restore them from a backup.
    3. Also, it's possible that the VM has been deleted. Please check the Hyper-V manager.
    4. Try to restart the Hyper-V Virtual Machine Management service.
    5. Ensure that the account you are using to connect to the Hyper-V server has the necessary permissions. Verify that you are a member of the Hyper-V Administrators group or have the required rights to manage virtual machines.
    6. If all else fails, you might consider reinstalling the Hyper-V feature on the server.

    I hope this helps!

    Best Regards
