Using a graphical user interface

The Sysinternals TCPView tool is a graphical interface that displays all of the active connections on a host. It displays all of the connection information you might need, including process name and ID, protocol, local address and port, and remote address and port. It is a real-time tool, so it shows connections that are terminating in red and new connections in green. You can close a connection by right-clicking it and selecting Close Connection. You can also kill the associated process by selecting End Process.
