The most likely reason for this.... assuming you are using a hard wired connection from 2nd pc to router, is the internet settings. These can be found by clicking on tools at the top of the page (internet explorer)followed by internet options, click the security tab,click the "custom level" button and work your way down the list to "enable each setting, set the "java permissions setting to medium safety, set the software channels" to medium safety, set the "user access log on " to anonymous log on, click apply and then ok the pop up security box. Then try and connect to the net.
