We are big users of .NET Remoting, and have recently noticed that our server processes all have two active listening ports, appearing in netstat and Resource Monitor. We are only registering one TcpChannel on a predefined port in our code, and can't work out what the second (apparently randomly allocated) listening port is. Can anyone help and/or point to some technical documentation that covers this? I've not been able to locate anything to date.
Many thanks.
