How do I find which application is using up my port? [closed]

How about netstat?

The command is netstat -anob.

(Make sure you run command as admin)

I get:

C:\Windows\system32>netstat -anob

Active Connections

And If you want to check for the particular port, command to use is:netstat -aon | findstr 8080from the same path

To see which ports are available on your machine run:

C:>  netstat -an |find /i "listening"

It may be possible that there is no other application running. It is possible that the socket wasn't cleanly shutdown from a previous session in which case you may have to wait for a while before the TIME_WAIT expires on that socket. Unfortunately, you won't be able to use the port till that socket expires. If you can start your server after waiting for a while (a few minutes) then the problem is not due to some other application running on port 8080.
