Our security software popped up complaining about a .DLL file. The .DLL file was directly affiliated with the printer that was installed on the computer. After getting these errors and rebooting, suddenly we're locked out of the system.
Local access does not work.
Domain accounts do not work.
"The system cannot log you on due to the following error: Access is denied. Please try again or consult your system administrator."
I booted to safe mode. Local access works fine. I even reset the administrator password from that screen and tried to log on in regular mode locally - no dice. I even created a new account in safe mode and tried to log on in regular mode locally - also no dice.
In safe mode, I can see the individual's profile. So it's an option (and one we'll probably act on) to copy the profile, re-image, and re-deploy the profile so it's back to normal.
Thing is, that doesn't "solve" anything. It's just a fix/workaround.
Any ideas?
