I've tried that.
a) I booted in standard safe mode. Logged in w/ user Administrator -- "Your account has been disabled. Please see your system administrator." I'm pretty sure the password is <ENTER> since that gives this error and anything else tells me I have the wrong user name / password.
b) I can't manage anything with Local Users and Groups when logged in as USER, because standard users can't create administrators.
c) I can't boot to a command line. "You need to sign in as an administrator to continue. But there aren't any administrator accounts on this PC."
d) I tried again in Networked Safe Mode. I still could not log in as Administrator and trying to do a HERE.LOCAL account got the trust error message.
I appreciate the effort.
