Hy,

I just disabled my firewall an I want to know how can I find TCP/UDP ports used by an application started lets say: messenger with all his services

I wanna know which ports the app uses.

Thx

Running netstat -o in a command prompt will show you open connections, and the PID of the application responsible for the connection.

Or you can try app like SIW [freeware, portable - does not instal].

Click on the - Open Ports - it shows apps, ports - you can export it.

or TCPView - formerly from Sysinternals, now M$ has their paws on it.

Or Google! I generally use netstat -o or Wireshark sniffer.

...or TCP Monitor

Another vote for TCPView.
