I just formatted a hard drive with XP home and updated with service pack 3 and .NET framework from the installation CD. Now the thing will download updates but fails on any of them - express, custom, necessary, software, and hardware. I was just browsing around the manage options on right clicking my computer on start menu. I see this anonymous logon entry every so often. If someone has the IP address can they hack into the machine by altering some kernel file in the system folder? If not, what if they also had the MAC address of the ethernet adapter on the board? Can you hide the computers MAC address behind the address of a wireless router?
