Open up a command prompt:
- Start | Run | type cmd | Enter
- Type netstat -aon | findstr “[port number]“
- Take note of the numbers on the last line. This is the PID or Process ID.
- Type tasklist | findstr “[PID]“ and this will return the application corresponding to that PID.
- Once PID is determined, you can now kill it in Task Manager or kill it typing tskill at the command prompt.
For example:
- I type netstat -aon | findstr “8080″ at command prompt (I’m on a proxy by the way)
- I see that the PID is 3624
- I type tasklist | findstr “3624″ to find what PID 3624 is and it points to msnmsgr.exe which is MSN/Live Messenger.
- I can now kill MSN Messenger from Task Manager or type tskill 3624
