I have just recently installed a RODC in a remote office. Our VPN connection to the main office is not operational and when I try to log into the RODC I get the "no logon servers are available...". I've tried to log onto the server with the local admin but the 'wrong password' error keeps coming up. I know 100% the password is correct. How can I log onto the RODC to administer it while my VPN to the main DC is down?
