ntuser.dat file deleted. How can I repair the user profile?

[Cristi]

Hi all,

I can login only with temporary user profile.
I discover that the reason is: the ntuser files from the user account were
deleted.
There is any chance (changing the registry, etc.) to do the system to
reconstruct these files - of course without loosing the user profile settings?
Any other solution to restore the user profile?
I notice that the status for this user profile is 'backup', the others are
'local'.

Best regards,
Cristi
