TCPView - Portable Endpoint Process Monitor

TCPView is a portable tool that can be used to display a detailed list and current state of all TCP and UDP endpoint connections and the process name running each endpoint. TCPView provides more informative information than the Netstat program that ships with Windows and includes a command line version called Tcpvcon that offers the same functionality. This portable Connection Monitor requires 328KB for complete stand alone portable installation.
