I don't know if you are looking for simple monitoring or more advanced programming, the later is usually able to be purchased off of the internet, and the former is usually available with you version of Windows.\n\nControl+Alt+Del will often bring up the option to use Windows Task Manager, and you then select the Networking Tab.\n\nHope this helps....\nMore options are available at the Command Prompt, but this usually takes a more experianced user, once in the CMD prompt, type help in order to veiw the list available to use.

You can use Ethereal to capture the packets from just before the game starts up to a bit into the game.  Then look at the capture.  It'll tell you what is running on what port, the protocols, etc.

You can do many things for this.  There are a lot of free/shareware/and programs for sale that do this exact thing.  otherwise you can DIY rather simply.  Go to start, run and type in cmd to get the command prompt (its also under all programs)  then type tracert (trace route) this will allow you to trace ever address that your network runs through basically by sending out a ping that bounces off the network addresses and returns the info.  You have to supply a target address for this to work properly.

get in to your router. type your router address at ur web browser (eg.192.168.1.1). usually your router can show you how many computer are connected to it. Or use a sofware like Network magic. u can found it at www.downloads.com
