Looked into changing the boot order in Windows. Right clicked "My Computer", selected "Properties". Clicked on "Advanced","Settings", "Startup and Recovery" as prompted, then asked to choose the desired boot system from a list on the drop-down menu. Found there to be two, but both identical. Both reading Windows XP MCE.
Just a wild idea and probably completely wrong, but could one of these possibly be false and the DHCP Server be trying to communicate with a "Phantom" version of my OS. Or am I completely barking up the wrong tree right now, while desperately clutching at straws!
