Do you mean the backup (connecting peer) cannot reach the master (accepting
peer) even if they are on the same machine? Are we talking about loopback
interface? This sounds quite odd to me...

Just to isolate problems, can you try to write a simple winsock program that
does following simple things: 1)listens on 127.0.0.1, port X, and 2)
connects to 127.0.0.1, port X.?

socket for transmitting to the Master.  (In this case, they are on the same
machine.  That is, the machine goes out to the network to send itself a
message.)   The program reads the registry to determine the machine IP and
Port which are specified as 127.0.0.1 and 22111, respectively.
