(If i recall correctly ...)

I think that with LANMAN encrypted authentication the password is
uppercased before the password hash is generated. This means that when
you log on from a Win9x (or older)  client the password is
case-insensitive. The "attempting-to-crack-the-password" thing doesn't
happen, because the smbpasswd file contains a LANMAN hash that is
calculated the same way that Windows would have done it.

NT passwords are not uppercased before hashing, and do appear to be case
sensitive.
