    Windows update: Error 1601: Failed to retrieve WMI info: The RPC server is unavailable (exception from HRESULT: 0x800706BA

    “RPC server is unavailable” is typically caused by one of the two following things:

    1. RPC (remote procedure call) service is not running on the target computer. Make sure the service is started and set to ‘Automatic.’

    2. Windows firewall, a third-party software firewall, or a network firewall is preventing RPC communication to the target host. Either disable the firewall altogether or make sure it is set to allow RPC communications pass through. For instructions on configuring Windows firewall to work with BatchPatch, see this page: Using BatchPatch With Windows Firewall
