Hello @Sunirmal Chakraborty ,
Thank you for posting here.
Based on my test in my lab.
1-I installed RSAT on one non Domain-joined Windows 10 machine.
2-Then I should set Preferred DNS on this non Domain-joined Windows 10 machine.
Tip: I have two DCs in a.com, they are both DNS servers and DC servers (the IP address of them are 192.168.3.50 and 192.168.3.57).
3-I open AD Users and Computers. I right click Active Directory Users and Computers and click Change Domain, then I type a.com and check "Save this domain setting for the current console".
4-I will view/manage all objects on one DC in the domain.
In my case, I can create a domain user.
Hope the information above is helpful to you.
Should you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
