Domain controllers are the backbone of a Windows network. They are the servers on which Active Directory (AD) and other critical directory services are run.
DNS is an essential part of AD, and it is important that domain controllers have a good DNS implementation.
Domain controllers should have a good DNS implementation because:
Domain controllers should have a good DNS implementation because they are responsible for the resolution of DNS names. If the DNS resolution on a domain controller is not good, users might not be able to access the resources they need on the network.
A good DNS implementation on a domain controller includes the following:
The domain controller should have a good DNS implementation and should be configured to use the latest DNS servers.
The domain controller should have a good DNS implementation and should be configured to use the DNS servers that are closest to the users.
The domain controller should be configured to use a primary and a secondary DNS server.
The domain controller should be configured to use a DNS zone that is tailored to the organization’s needs.
The domain controller should be configured to use a DNS zone that is tailored to the organization’s domain name.
The domain controller should be configured to use DNS forwarders to improve the resolution of DNS names.
The domain controller should be configured to use a dynamic DNS server to improve the resolution of DNS names.
The domain controller should be configured to use a security protocol, such as Secure Socket Layer (SSL), to protect the DNS servers from attack.
The domain controller should be configured to use a security protocol, such as Kerberos, to protect the users from unauthorized access to the DNS servers.
The domain controller should be configured to use a password to protect the DNS server from unauthorized access.
The DNS server should be configured to use forwarders to improve the resolution of DNS names.
The DNS server should be configured to use a dynamic DNS server to improve the resolution of DNS names.
The DNS server should be configured to use a security protocol, such as Secure Socket Layer (SSL), to protect the DNS servers from attack.
The DNS server should be configured to use a password to protect the DNS server from unauthorized access.
The DNS server should be properly protected by using a firewall.
The DNS server should be properly configured to use encryption, such as Secure Sockets Layer (SSL).
The DNS server should be properly configured to use a compression algorithm, such as Zlib.
The DNS server should be properly configured to use a logging facility.

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.
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.
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.
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.
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 controller DNS should point to itself in order to optimize DNS lookup performance. This is because the AD DS server is the authoritative source for the AD domain. If the AD DS server is not available, then DNS queries for the AD domain will be directed to the local DNS server.
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.
A common question is whether domain controllers should be DNS servers. In general, the answer is no. Domain controllers should not have the responsibility of providing DNS service for the domain.
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.
