Unable to Logon interactively using any account

Hi,

I have a Windows XP Pro machine that will not let me logon with any
credentials supplied. When I attempt to use a domain account
(administrator or user) the machine tells me that the specified domain
does not exist. If I try to logon with the local administrator account
the machine tells me that I am not allowed to logon interactively.

Things I have tried:
Replacing the security via the recovery console
Booting into safe mode

I don't know what to try next. I don't want to rebuild the workstation
becuase there is data I need to recover.

Any help would be greatly appreciated!
