I have a Silverlight 5 App running in browser that needs to access LocalPort (between 4502 and 4531) on client's machine.
I do know for sure that PolicyFile.xml must exist that will grant the required permission for the Silverlight App. I also realize that the Silverlight App first pings port 943 to know if it has the required trust/permission to access local ports.
My question is, is this port "943" on the Server where the application is hosted or is this on the user's machine where the Silverlight app is running?
