I have a box running Windows Server 2012. I have been playing with this box for a bit and have two admin accounts set up: administrator and my account. I recently had to change my password due to policy. I set a new one, updated in my password manager, logged out, and tested. It all worked for a couple weeks. Not today. I cannot log in through Remote Desktop or through the Launchpad from my machine as either account, using the domain or server name with the account. But, there's a catch.
Through RDC I can plug in the administrator credentials and get to the machine, but it's login screen says my user and password are incorrect. Why would RDC connect? Of course, I figured I'd just log in as the administrator account and reset my password. So much for that. I hope I'm missing something simple and obvious.
