upgrade from Win98 to W2K Pro, password problem

Archived from groups: microsoft.public.win2000.setup_upgrade (More info?)

Hello,
I have yet another password issue that requires some
help. I just upgraded an old computer from Win98 to W2K
pro. Everything seemed to go just fine until it was time
to log in after the setup was completed. I get the log in
screen, enter the password, it says it is check
preferences then saving preferences, and then goes back to
the log in screen.
I have tried to bypass it to re-load w2k with no luck. I
tried to use fdisk\mbr but can't get to a prompt, I tried
just using a blank space for admin login and that didn't
work. I am also using the setup boot disks in an attempt
to use some password bypass hacking software to get past
it, nothing yet. Anyone have any ideas?
