Cannot join a domain with multiple DNS servers configured on client NIC RRS feed

  • Question

  • I am doing a migration in a network, users already joined the domain but they use proxy for internet.

    The new setup includes removing the proxy, I give clients two DNS :The primary is the DC for local domain, and the secondry (8.8.8.8) for Internet.

    The issue now is the client is not being able to join the domain.

    when I remove the secondry (8.8.8.8), the client is able to join the domain but cannot reach internet.

    The situation you descripts is a common issue, although there's no convincing reason to explain it, while it generally behaves like this. When we configure both domain DNS and public DNS on client, although make domain DNS as preferred DNS, the client will contact public DNS first.

    Generally, we will only configure domain DNS(DC) as preferred DNS on clients, then configure public DNS server as forwarder on domain DNS server. For example, client 192.168.2.1, DC 192.168.2.5, public DNS 8.8.8.8. On client, only configure 192.168.2.5 as DNS server; on DC, open DNS console, click forwarder, add 8.8.8.8 as forwarder; in this way, domain clients will not have DNS resolution issues and also can visit Internet.

    Best Regards,

  • Hi Ahmed,

    Your DNS servers are they configured with root hints? I would just use your two dns ip address for your clients. You can configure forwarders to use the 8.8.8.8 & 8.8.4.4 in DNS to lookup external dns names, look here to configure.
