Step-1(Server_2016)

-------------------

Go to Server 2016.
You must change the server name. In my case server name is "server2016".
Now you must create ADDS in server 2016 machine. In my case domain is "server2016.act.local" .
You must create OU with user in server 2016 thereafter go to domain controller and you will see only one server "server2016".

Step-2(Server_2019)

-------------------

Go to Server 2019.
You must change the server name. In my case server name is "server2019".
Now you must install the role of "ADDS" in server 2019 machine.
You must configure server 2019 such as "Additional Domain Controller(ADC)".
After complete it you must check the OU that is created in server 2016 and you will see that. Thereafter you must go to domain controller and you will see both server.

Step-3(Server_2016)

--------------------

You must create OU_(IT-Department) & create a User_(User-1) in OU.

In a domain controller you will see only Server 2016 before configuring the ADC & after configuration of ADC you will see both server.

In a Domain Controller you will see Infront of you both Server.
