using netstat on Windows

Netstat is always useful for finding open ports, whether a service is running as expected and so on. As listed at http://www.petri.co.il/quickly_find_local_open_ports.htm

netstat -ao |find /i "listening"

to find process id and open ports. Process id can be mapped to process name with Windows Task Manager, choose to view PID from View -> Select Columns.
