Domain controllers should have DNS enabled and configured to use the default domain name servers. DNS is a critical service that allows computers on a network to resolve domain names to IP addresses. By default, domain controllers use the DNS server located on the same network as the computer. However, if the network is not secure, the DNS server may not be a secure source of information.

By using the default domain name servers, the domain controller can trust the information it receives from the DNS server. Additionally, configuring the domain controller to use specific DNS servers can improve the performance of the network.
