hi all. suddenly winxp wants password at login when i never had one before. can't even get in with safe mode / administrator... keeps saying that local policies of this system require password. everything worked this morning, but now won't. no one has been here to mess with it. can't find virus information like this...... any ideas?
laptop w/xp home sp2
(not recent, done at least a month ago, in fact other than virus updates, no recent updates)
