Can't Login

Archived from groups: microsoft.public.windowsxp.general (More info?)

I have a XP Pro SP2 box that I can't get back into. During the istall
process, the first ID was created as "First M. Last-D" . After using this
ID, which automatically logged in, for about a month, I created a second ID
"Firstname" for a co-workser to use. Now when the original id is tried, it
says the username or password isn't correct.

I did login with the second ID and check the spelling of the name and reset
the password but still couldn't login.

This system is not part of a Domain, just a stand alone box. How do I login
using the ID "First M. Last-D" again?

Thanks
