Boot into in safe mode -if not any administrator account in safe mode
should appear build-in administrator.If build-in administrator is also
unavailable in safe you have to turn build-in administrator account
remotely

See below advices how to do that:'What do I do: I can no longer log in
or elevate to an administrator account'
(http://www.jimmah.com/vista/content.aspx?id=7)
and
http://www.vistax64.com/tutorials/20...ge-win-re.html

apart of above methods alsoTools for reseting password also have
option to enable/disable accounts (for built-in admin also) for example
'Offline NT Password & Registry Editor'
(http://home.eunet.no/pnordahl/ntpasswd/)
If you have been degraded to limited user you can also use this tool to
add yourself to Administrators group
