Introduction to Error Code 800706BA

Unfortunately, there are many causes of error 800706BA.  I solved my problem by disabling the firewalls.  See how to disable Windows 8 firewalls with a Group Policy.

The Symptoms You Get With 800706BA

My situation was that was running the remote PowerShell command restart-Computer when I got this error message on the Windows 7 machine:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

The Cause of Code 800706BA  

The underlying cause of my problem was WMI.  I was using PowerShell cmdlets such as get-WmiObject that were trying to access data on another Windows 7 computer.  What happened was that the firewall was correctly, blocking the RPC ports 135 and 445.  Thus I simply disabled the firewall on the target machine and the command then completed successfully.
