Determine Which Applications Are Connecting To The Internet

All you need to determine which of the applications running are connecting to the Internet is a DOS prompt, thanks to the netstat command. Thus fire up a DOS window by entering “command” in Start Menu -> Run and type netstat -b. Wait a couple of minutes as new connections are being open by your currently running applications. You’ll end up with a list similar to the following:

Results of netstat -b

You can go more advanced and have the application monitor the connections every 5 seconds, as well as write the log to a text file. For that, you need to use this command:

netstat -b 5 >> C:\netstat_log.txt

When you’re tired of this, you can close it by pressing Ctrl+C.
