Domain controllers provide DNS services for their respective domains. By default, the DNS servers for a domain are registered with the DNS servers for the domain controller.
When you add a new server to your domain, the new server registers itself with the domain controller as the DNS server for the domain. If the domain controller fails, the new server can continue to serve DNS clients by registering itself with the DNS servers for the domains that it replaces.
The DNS servers that a domain controller registers with are called the primary DNS servers for the domain. The primary DNS servers are used by the domain controller to resolve domain names to IP addresses.
The domain controller also uses other DNS servers, called secondary DNS servers, to resolve domain names when the primary DNS servers cannot be used. The domain controller uses the IP addresses of the secondary DNS servers to resolve domain names.
A domain controller can also use the DNS server of a remote domain to resolve domain names. When you create a trust relationship between two domains, the remote domain server becomes the primary DNS server for the trust domain.
The domain controller uses the IP address of the remote domain server to resolve domain names.
A domain controller can also use the DNS server of a remote Active Directory domain to resolve domain names. When you create a trust relationship between two Active Directory domains, the remote Active Directory domain server becomes the primary DNS server for the trust domain.
The domain controller uses the IP address of the remote Active Directory domain server to resolve domain names.
A domain controller can also use the DNS server of a remote forest to resolve domain names. When you create a trust relationship between two forests, the remote forest server becomes the primary DNS server for the trust forest.
The domain controller uses the IP address of the remote forest server to resolve domain names.
A domain controller can also use the DNS server of a remote domain to resolve domain names when the domain controller is part of a federation.
A domain controller can also use the DNS server of a remote Active Directory domain to resolve domain names when the domain controller is part of a federation.
A domain controller can also use the DNS server of a remote forest to resolve domain names when the domain controller is part of a federation.
A domain controller can also use the DNS server of a remote domain to resolve domain names when the domain controller is part of a Kerberos realm.
A domain controller can also use the DNS server of a remote Active Directory domain to resolve domain names when the domain controller is part of a Kerberos realm.
A domain controller can also use the DNS server of a remote forest to resolve domain names when the domain controller is part of a Kerberos realm.
A domain controller can also use the DNS server of a remote domain to resolve domain names when the domain controller is part of a replicating domain controller configuration.
A domain controller can also use the DNS server of a remote Active Directory domain to resolve domain names when the domain controller is part of a replicating domain controller configuration.
A domain controller can also use the DNS server of a remote forest to resolve domain names when the domain controller is part of a repl.
