It is used for finding problems in the network and to determine the amount of traffic on the network as a performance measurement. [wikipedia.com]

Parameters used with netstat command are:

netstat /? Output

In case you want to kill a process without knowing its name and the only information you’ve got is a port number; there’s no need to worry about it. Here are the six simple steps in KILLING A PROCESS BASED ON A SPECIFIC PORT NUMBER.

6. Kill the process base on PID

If you want to change a port number, you may edit services file located on C:\WINDOWS\system32\drivers\etc
