Today I was trying to connect with Remote Desktop from a Windows Server 2008 host to a Windows Server 2012 R2 host, but connection after entering password didn't succeed.
The error was "An authentication error has occured (Code: 0x80090304)." I had never seen such error before. The error translates as "The Local Security Authority cannot be contacted".
After some troubleshooting I decided to reset the password, which did the trick. I was able to connect afterwards :)
