Every had an issue whereby you are trying to run a n application and its says unable to start because the port is in use by another application? example tried to launch th eUnify Controller software by Ubiquity and got the error that the port was in use by another application. To find that application go to

run -> type cmd then press enter. 
they type netstat -ao | find "8443" whereby 8443 is the port number. you will see a result like this;

Microsoft Windows [Version 6.3.9600]
(c) 2013 Microsoft Corporation. All rights reserved.

C:\Users\PC>netstat -ao | find "8443"
TCP 0.0.0.0:8443 jdam:0 LISTENING 2400
TCP 127.0.0.1:8443 jdam:65361 ESTABLISHED 2400
TCP 127.0.0.1:65361 jdam:8443 ESTABLISHED 8400

C:\Users\PC>

To the extreme right of each line is the PID of the application running and using that port. Simply open the task manager and ensure the column heading "PID" is selected then look for the application and end the task. Your application will not run.
