Después de aplicar la actualización de Windows Server 2016 del 9 de abril KB4493441, al intentar acceder al administrador de Hyper-V aparece el siguiente error:

An error occurred while attempting to connect to server “NombreServidor”. 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 ‘NombreServidor’ because the object was not found. The object might have been deleted. Verify that the Virtual Machine Management service on the computer is running.

Para solucionarlo deberemos ejecutar, con permisos de administrador, el siguiente comando:

MOFCOMP %SYSTEMROOT%\System32\WindowsVirtualization.V2.mof
