Cannot logon to new home network connection?

[Timothy Moore]

My computer uses domains to logon to the o/s, I had
recently tried to creat a new network connection with
unchecking the option for "this computer logs onto a
domain". After new connection was made, the computer asked
to be rebooted, without giving me the chance to choose a
User and password. Now when rebooted, the domain option
in the logon screen has disappeared and I have no User
Name and Password to logon to the new network connection.
I have tried my existing User/Pass, but without the Domain
Option, the login information is invalid. My questions
are. How do I login now to undo the new network
connection? Or how do I tell the computer to logon to a
domain, so that my Administer User Name and Password are
valid once again?

You need to login with the 'local' administrator account
and password.

This is probably still the same administrator password
that was set when the operating system was installed. It
is completely separate from the administrator account and
password for the Domain.
