This tool is handy if you’ve ever encountered unexpected TCP port conflict exceptions when attempting to create a client socket connection. Depending on your environment, the exception text will look one of two ways.
The problem is two-fold. First, Windows only makes a certain number of ports available to client sockets – the default is in the range of 1024 to 5000. Hence, you may have only 3,976 active client connections at a time. For most systems, this is plenty. However, in specific circumstances on systems requiring a large number of outbound connections, this limit can be exhausted.
