FIX: RPC server unavailable OS error 0x800706ba | Sonicwall Unauthenticated Users | Fix Port for WMI

In this video I am going to show you how to fix the below errors

1. Sonicwall : SSO agent reported: OS error 0x800706ba: RPC server unavailable
2. Error: The RPC Server is Unavailable
3. SSO agent reported Network Path Not found
4. Error: WMI Error: 0x800706ba, The RPC server is unavailable.

Cause: Windows 10 and the latest windows randomly changes WMI ports which are mostly blocked by Windows firewall default policy. So in order to fix one port to WMI follow the below steps and allow that port in Windows firewall Inbound as TCP.
------------------------------------------------------

Copy paste below CMD commands (Run as Admin CMD)
1. winmgmt -standalonehost
2. net stop "Windows Management Instrumentation",
3. net start "Windows Management Instrumentation"
4. netsh firewall add portopening TCP 24158 WMIFixedPort
