PC repair work

Mark came over, bringing his Compaq PC which has been behaving oddly. A little exploration revealed that all kinds of vital files had been deleted from the hard drive—some DLLs needed for Windows domains, a few key bits of Internet Explorer, and the whole of Outlook Express, for example. After half an hour or so fiddling with the Network control panel, rebooting, then fiddling with it some more, I managed to get the machine to request an IP address and join the network.
