one small note that was left out of the above video, at the 5:15 mark the video mentions changing the IP address to an address on your network, this is correct but at the same time that you change this you will want to double check that the gateway box has the correct address in it so that it matches the address of your network's gateway/router.
(you'll find the gateway address of your network when you do the 'ipconfig' search with command prompt)
