    Create a rule where the listener is "SYSTEM"


      I am trying to enable BranchCache in my environment.  Branchcache requires the client to be able to receive traffic on port 80 from the local subnet to the [System Process]  PID 4.


      I tried creating a rule with SYSTEM as the executable name, but that didnpt work.


      I called in to tech support, who told me there's no way to have a firewall rule that targets SYSTEM and that I would have to open port 80 to all processes if I wanted SYSTEM to be able to respond to traffic on port 80.


      Is this true?  Is there really not a way to open System to port 80 without opening port 80 to all processes?
