I just installed FC3 a few days ago on a computer that formerly ran Windows XP. In the install, I had the old OS deleted. I just recently rebooted my computer, and the old harddrive name I used in XP has suddenly become my computers name in FC3 !!!!!!!!! Everything seems to work fine, but upon bootup, I get a message telling me the computer can't find an internet address for this old name, and maybe I should add it the the etc/host file, and gives me the choice to 'try again' or 'login anyways' (this is a paraphrase of the message).
What the heck is going on and should I be worried? What should I do?
Thanks.
