On my Windows 10 Enterprise technical preview machine (build 10049), it locked out after inactivity and now only offers the option to login with "Other user". On this screen, it only seems to want a Microsoft account, although if I enter a valid Microsoft account it says the password is wrong. It won't accept a domain account, and it does not seem to offer any way to switch to the normal domain login screen.
I am locked out of the PC and unable to use it. When I reboot, it goes back to the same login screen.
Help!
