How to identify what service is listening on what port?

Open a command prompt and type

Netstat -ano

This command outputs a list of all listening ports, associated process IDs, and the port number

Now run

tasklist /svc

This will give you the service name that maps to a particular PID

Further to above, a "new" option, -b, is available in netstat command after Windows 2003 SP1. This will show you what image occupies which port.
