Check TCP/IP port availability

If the Recording Service website does not open after the installation is complete, the problem may occur due to the busy TCP/IP port specified during installation.

To find open ports on a computer and to check what application is using specified port, use the netstat command line:

Open the command prompt (Start > Run > cmd) and use netstat -ano | find /i "<port_number>".
It will show you all processes that use the specified port. Notice the PID (process id) in the right column.

• -a – Displays all active connections and the TCP and UDP ports on which the computer is listening.
• -n – Displays active TCP connections and port numbers in numerical form.
  If you would like to free the port, go to Task Manager, sort by PID and close those processes.
• -o – Displays active TCP connections and includes the process ID (PID) for each connection.
