If you understand that logon without a doman controller can only be
accomplished with administrators and previously logged on users. If a user
has logged on, his credentials are stored and authenticated by the Local
Security Authority... To stop this you can set AD so that windows does not
store the profiles... by default I think it stores 10 (meaning it will store
the last 10 users logged in)... You can set this to "0"... Secondly, I would
set up a very restrictive local policy... basically without the domain
controller you can do nothing...
