NT can always log in locally. If the option has been removed from the logon prompt (no easy task, it took me awhile scouring the registry to figure out how), you can still specify it by using localhost/%username% in the user field.
You should also note that the local computer name will appear in the domain field, though it is not a domain. A domain name of "KFIAPLORL45127" makes me think that it is probably the computer's netbios name, randomly generated. Which means you are attempting to log in locally anyway.
