stuck in workgroup, need to get back to domain

[Goodman]

Windows XP user, trying to set up family sign-on in workgroup. I logged out of domain, into workgroup, unfortunately, I signed on as a guest, not the administrator. Now I'm stuck. In the domain logon, I have administrative priveledges. I thought I coul
d log off, then sign on to domain using "DOMAIN\username" for username then entering my password. But I'm not being granted access. How do I get the option of signing back onto my domain.

You need to bring the computer back to work and ask the domain admin to
rejoin your computer to the domain.
