Lock out of XP Pro after formatting Windows 2003 Server

[Trimelater]

I have a server where the domain controller is called ARC. I formatted the
server to increase the partition of the C: drive. After reinstalling the OS
and using the same name called ARC again. I am not able to logon to XP Pro
only if I changed the user named. I believed the current username is cache
which enables the user to logon. If a different user logon, then the cache is
lost and there is no means to logon.

Well, my stupid thinking said, why don't remove the domain and join a work
group and then rejoin the ARC domain. After reboot, I can't logon and I
don't have the administrator password.

I will attempt to logon as a "Guest" which I doubt I can do anything with
it. Please let me know if there is any means to logon locally and allow
myself to rejoin the domain again.
Is there any solution where I can avoid reinstalling the O/S?

How about the trusty old Nordahl boot disk?
