Winsock applications can specify what UDP ports they listen on. You can use the NETSTAT utility with the -an option to display the status of a socket. However, NETSTAT -an may display both UDP and TCP listening on the same socket when only UDP is bound to the socket.
NETSTAT [-a] [-n] -a Displays all connections and listening ports. Server-side connections are normally not shown. -n Displays addresses and port numbers in numerical form.
This behavior does not affect socket connections, but is simply a display. problem.
Microsoft has confirmed this to be a problem in Windows NT version 4.0.
