ntuser.dat, and ntuser.dat.log files are used by your computer registry.
It looks to me, that your registry got messed up.
Can you access Windows at all?

Another great argument for diligent backups...
Do you have a Windows XP CD ? ?
Not to concern you but recently i have seen lots of troubles related to UniBlue...

You will have to give info on your computer to get your problem fixed, Do you have the XP CD? Can you log on your computer or is this a post from alt computer?
