How does Windows decide whether your computer has full Internet access?
I suppose you could spoof having full Internet access by hosting <i>nsci.txt</i> or <i>connecttest.txt</i> locally and editing your hosts file to direct <i>www.msftncsi.com</i> or <i>www.msftconnecttest.com</i> to <i>127.0.0.1</i>? Conversely, if those Microsoft websites ever failed, countless Windows machines would determine that they have limited or no Internet access.
