Domain controllers are servers that act as the primary control point for a domain, and are responsible for ensuring that all DNS requests are handled correctly. By running DNS on a domain controller, you can ensure that all requests are handled correctly and that your domain is fully operational. However, there are a few drawbacks to running DNS on a domain controller. First, domain controllers are often the most expensive server type to purchase and maintain, and their performance may be impacted by the addition of DNS components.
Second, if a domain controller is offline or unable to process DNS requests, your domain may be unable to function. Finally, if a domain controller is compromised, DNS requests may be directed to incorrect servers, which could lead to security vulnerabilities. Overall, running DNS on a domain controller is a viable option, but there are a few important considerations that should be taken into account before making the decision.

There are pros and cons to having DNS servers on domain controllers. On the pro side, domain controllers are typically more reliable and faster than standalone DNS servers. They can also handle more requests simultaneously, which can result in faster DNS resolution times.
DNS Needs to Be on a Domain Controller
There are a few reasons why DNS needs to be on a domain controller. First and foremost, DNS is a critical service that is used to resolve domain names into IP addresses. If DNS is not running on a domain controller, then users will not be able to access their domain names or other resources.

The history of DNS and why it is important
Domain name systems (DNS) are essential for the functioning of the Internet. DNS is a hierarchical system that maps names (such as www.google.com) to IP addresses. When you type the name www.com into your browser, your computer consults DNS to find the IP address for that site.
There has been much debate recently as to whether or not a Domain Controller (DC) should point itself to the DNS servers for the domain. This debate is based on the theory that if a DC is not authoritative for the domain, then users may not be able to access resources on the domain. However, there are also many other reasons why a DC might point itself to the DNS servers.
Domain Controllers should use themselves for DNS. There are several reasons why this is the best practice. First, it is a best practice to have a single point of administration for your DNS.
An authoritative DNS server can provide more reliable and secure DNS resolution for clients located behind a firewall. By default, a DNS server does not use its own address to resolve DNS queries, but instead relies on the addresses of other DNS servers. If the DNS server is located on the same network as the clients, this approach can result in DNS resolution that is faster and more reliable than if the DNS server is located on a separate network.
There are a couple of ways to answer this question. One way is to say that DNS does not have to be installed on a domain controller, but that it can be if desired. Another way to look at this question is to ask if DNS is required for Active Directory to function.
There is no one definitive answer to this question. Some factors to consider include the size and complexity of your organization’s DNS infrastructure, the amount of traffic your domain controllers are handling, the amount of redundancy your organization has in its DNS infrastructure, and the type of DNS services your organization uses. Ultimately, the decision whether or not to point domain controllers to themselves for DNS depends on the specifics of your organization’s situation.
Ensure DNS is configured on all domain controllers in your Active Directory forest. DNS is required in order to resolve domain name references to IP addresses. If DNS is not configured on a domain controller, Active Directory cannot resolve domain name references.
