SQL Server Configuration Manager returns remote procedure call failed
In my case there were two instances of the "SQL server Configuration Manager" in SysWOW64. Only the latest version worked. The other version produced the RPC error message. 

C:\Windows\SysWOW64\mmc.exe /32 C:\WINDOWS\SysWOW64\SQLServerManager10.msc FAILED
C:\Windows\SysWOW64\mmc.exe /32 C:\WINDOWS\SysWOW64\SQLServerManager11.msc WORKED
