I am having problems with a fresh installation as domain admin on a 2012 DC. The engine installs fine, but when logging in to the admin console, the setup mode fails. I can click next in the first setup window, but the following screen gives me the login screen again with the error: 'The data is invalid'. Proxy option is defined as 'no proxy'. Firewall is off.

I can only abort the setup from this point.

Any ideas?
