Adding new Domain Controller server into Existing Active Directory Domain Services with Windows Server 2019 Core

I assumed you had installed windows server 2019 with "Core" option instead of GUI, at least you have 1024 MB of RAM and 1 cpu.

Step#1: Configure Hostname, IP static, timezone,  DNS server.  I was using command "sconfig" to do that, you can use manual configuration if you like.

Step#2: install AD domain services binaries package using Powershell in new server :






Step#3: Join a new Domain Controller server  into existing AD Domain services :







Server will be rebooted after joined. you can validate service up and running after server rebooted :


Step#5: Verify whether it's joined into existing AD Domain Services or not. Open "Active Directory Users and Computer" from existing Domain Controller Server that has GUI or  "Remote Server Administration Tools (RSAT)".  Newly Joined Domain Controller server name: OSW2K19-DC03.



Step#6: Since it's been promoted as new Domain Controller server, you can change DNS server to itself and the alternate DNS server can be pointed to others.

How to ensure a new Domain Controller server replicate to others within Active Directory Domain Services (Windows server 2019)

Image
Once you added a new Domain Controller server,  you have to ensure it's been replicated to others to avoid data discrepancy happening.  Check "Replication Topology" & Run "Replicate Now " on each of Domain Controller server. I have two domain controllers: OSW2K19-DC01 and OSW2K19-DC03 that replicate each other, it depends on your Replication Topology anyway.   Open "Active Directory Site and Services" Tools from Server manager on Domain Controller server. I prefer GUI instead of command line to show you, easy & colourful :-D.  Right Click on NTDS Settings, All tasks --> Check Replication Topology on  OSW2K19-DC03 (Newly DC server) : Run "Replicate Now" : Right Click on NTDS Settings,  All Tasks --> Check Replication Topology on OSW2K19-DC01 (old DC server): Right Click on NTDS Settings, All Tasks --> Run "Replicate Now" : Check Replication Status (repadmin /replsummary ) from Powershell : show replication (repadmin ...
