Hello everyone, on the attached picture you can see the topology of my lab. I`m having troubles promoting the server called DC-2-2 to a domain controller for child.office-2.local. I got "The replication partner: DC-2.office-2.local shows replication errors." In the txt file you can find the output of "Install-ADDSDomain". I can not figure out how to use repadmin.exe to narrow down the cause of the issue. May I ask you for help? Capture

    Name resolution for the name _ldap._tcp.dc._msdcs.office-2.local. timed out after none of the configured DNS servers responded

    The DFS Replication service failed to contact domain controller to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. This event can be caused by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues.

    Hi, let me confirm if we are all on the same page. I have to make sure that the ports mentioned in the article that you provided are open on all Windows Firewalls in my lab, right? If so, is there a rule corresponding to each port that I have to enable or I have to create new rules?
