Madhans Firewall : Ports Opened

How lto find out which ports are open in a windows XP Computer?

In the dos prompt, type "netstat -a". you will get the output as shown in this screenshot.

To get the process id each application which is running on each port,

give the command like this : "netstat -NO".

But from the process id , how i can know the NAME of the application?

You can open the task manager and see the application name and process id.

But in my computer, when i open the task manager, it is showing the application names, but not the process id. what i should do?

Certain fields are not displayed by default. The process id is one of the hidden field. You click the checkbox as shown in this screenshot.
