Reading A 'Port'

I have an application that runs on NT Server (located on a network).  Users can connect to this multi-threaded application via a port number (e.g. 10020) defined in the services file using custom client tools running on NT Client. I would like to be able to monitor how many users had  'connections' at any given time.

check out this small project at:
It uses a RAS Api call to determine the number of connections
I'm assuming that you are using multiple winsock controls in your program. If that is the case you should be able to loop through the controls and check to see if someone is connected.

For i = 1 to WinsockControls.Count
  If WinsockControls(i).State = 7 Then 'Connected
    UserCount = UserCount + 1
  End If
