Answer 1

You can use Sysinternals TCPView application which gives you a nice graphical view of all of the network connections on your system.

Answer 2

Start, run, cmd

netstat -b

Answer 3

Nirsoft Currports

I prefer this one to Sysinternals TCPView because it have filters and logs features

Comodo Firewall

In "Custom Policy Mode" you will be prompted for authorization each time a program create a connection...
