Kill a process using a Port
This is gonna be a fast post, sometimes I get a error in NetBeans that says I can't run the application because the port 8081 is used by other app, then I have to kill that app. first we have to find it running the next command in a Console netstat -n -o This will print Protocol | Local Address | ForeginAddress | State | PID the important columns are " Local Address " where you will search for the port and " PID " that will show you the Process ID that is using it.. when you find it, type the next command changing the PID that is using the port in this case it is 5275 taskkill /PID 5272 if you get any trouble, add /F to force it to end. That's all.... Celebrate like kashiyuka because you killed that annoying Process and after do it 4 times more you will get a " Killing Spree " ;)
