In this article I am trying to determine which program (or process) is using port 3443
Step 1 Netstat
Open a cmd-promt and enter the command
netstat ano |more
Look for the port number and note the PID (process id).
Step 2 Task Manager
Open task manager. Go to the view menu and make sure the PID column is displayed.
Make sure you have selected “show processes from all users”
You can then locate the PID and view the corresponding process.
In this instance its BES-AS the blackberry application server.
