Resolve

Check nvspwmi service and WMI

The Network Virtual Service Provider Windows Management Instrumentation (NVSPWMI) service is used to control virtual network resources such as virtual switches, switch ports and internal Ethernet ports.

Check that the nvspwmi service is running. If this event still fires, run mofcomp against %systemroot%\system32\WindowsVirtualization.mof and  %systemroot%\system32\en-US\WindowsVirtualization.mfl and then restart the nvspwmi service. If you still see this event, re-install Hyper-V.

By default mofcomp.exe can be found in c:\windows\system32\wbem.

To restart NVSPWMI using the Service Manager:

1. In the Hyper-V Manager click the server on which you want to stop the service, then click Action, then click Stop Service.

2. Click Action,  and then click Start Service.

To restart NVSPWMI using PowerShell:

1. On the computer that has the stopped service, open a command prompt as local administrator and type the following:

C:\PS>restart-service nvspwmi

To restart the NVSPWMI service using the command prompt:

1. On the computer that has the stopped service, open a command prompt as local administrator and type the following:

net stop nvspwmi

If the service is not running, you will see the error "The Hyper-V Networking Management service is not started."

2. On the command prompt type the following command to start the VMMS service

net start nvspwmi

 If the service start starts you will see the message "The Hyper-V Virtual Networking Management service was start successfully."

Verify

The user is able to succesfully create and manage virtual switches through the user interface (UI) as well as through the WMI interface.
