Just try to prompt a windows server 2016 to DC in an existing windows 2012 R2 DC environment. The AD service is running and domain controller lists the windows 2016 as dc. However, Task Details and Notifications shows “Post-deployment configuration. If you double click on it, I get this: “Error determining whether the target server is already a domain controller”. I have rebooted the server twice. Please any suggestions?
Troubleshooting:1. restart the server.
2. Or Waited for half hour. The error disappear.
