passwork no longer works after change 'domain' to 'workgroup'

[tyson]

I've a username ABC registered in a domain DEF. At
welcome login menu, I can login ABC with password XXX.
Then I changed from Domain to WOrkgroup, then reboot. I
no longer can login with username ABC with password XXX.

What can I do?

Thanks in advance.

If you disjoin the PC from domain you can't use domain passwords any more.
One thing that you can do is at welcome screen press twice (!) ALT+CTRL+DEL
and you will get standard logon screen... Use administrator account that was
created when you first set up the PC...

Take the computer back to the network where the domain is, and ask the admin
to rejoin the computer to the domain. No offense, but this is one of the
many reasons why it is generally not recommended to grant user accounts
local admin rights - this happens all the time when users who don't
understand their network setup want to use their work laptops on their home
networks - it isn't at all necessary to change the domain membership in
order to do that!

Greetings --

By changing the computer from the domain to a workgroup, you have
destroyed the trust between the domain and the machine. In doing so,
you have also rendered any domain login credentials as invalid. You
need to be physically connected to the domain network, you need to
have administrative privileges to the workstation, and you need to
have administrative privileges on the domain. Then you can add the
machine back on to the domain, after having first deleted the
computer's old domain account (unless you've also renamed the
computer).
