I installed a fresh Server 2012 R2, no modifications, no updates. I used Server Manager to install Active Directory Services (together with DNS-Server). I used the promotion wizard to configure a brand new domain (first server in new domain). Everything went fine and the server was rebooted automatically.
A BSOD appeared, error no 0xC000021a and that´s it.
I´m working on this for serveral days now. I tried every hint I found in the forums, checked event viewer, checked log files, checked mini dump file, ran SFC /scannow and DISM RestoreHealth, not a single error.
The only thing that´s working: I can start the system to the last known good configuration. Checking services I see: DNS server is not installed and Active Directory is deactivated. Activating/starting AD services ends up with no error and AD is stopped immediately.
I have no more ideas and appreciate any help.
