in cmd prompt, use:

netstat -a -n -o

If it does not show up, it is not in  use. However if you do see it, use the PID and run "tasklist" to track down what app may be using it

Filtered means it is listening but a firewall is blocking the responses

Hi,

It is possible that Windows Firewall might be blocking it, if there is no service using that port for security purpose.

Add a port to the Windows Firewall exceptions list

Hope that helps :)
