Should all domain controllers run DNS?

Posted on


Proper domain controller DNS setup is vital for Active Directory to work properly. Best practice dictates that each domain controller should be setup with a different DNS server as it’s preferred DNS server, and and the loopback address (127.0. 0.1) as it’s alternate DNS server.

Should all domain controllers be DNS servers?

In a small environment, at least one domain controller (DC) should be a DNS server. It is possible to install DNS on servers which are not DCs, including non-Windows servers, but installing DNS on DCs allows the use of AD-integrated lookup zones (see below), which improve security and simplify zone replication.

Do domain controllers run DNS?

In addition, domain controllers use DNS to locate each other. The DNS Client service is included in all client and server versions of the Windows operating system, and is running by default upon operating system installation.

Why DNS server is required for Active Directory?

Active Directory Domain Services (AD DS) uses Domain Name System (DNS) name resolution services to make it possible for clients to locate domain controllers and for the domain controllers that host the directory service to communicate with each other.

Should DNS and DHCP be on the domain controller?

Domain controllers do not require the DHCP Server service to operate and for higher security and server hardening it is recommended not to install the DHCP Server role on domain controllers.

How many DNS servers are needed?

At a minimum, you’ll need two DNS servers for each Internet domain you have. You can have more than two for a domain but usually three is tops unless you have multiple server farms where you would want to distribute the DNS lookup load. It’s a good idea to have at least one of your DNS servers at a separate location.

What should be the preferred DNS server on a domain controller?

Domain controller without DNS installed A local primary and secondary DNS server is preferred because of Wide Area Network (WAN) traffic considerations. If there’s no local DNS server available, point to a DNS server that’s reachable by a reliable WAN link.

Best practice dictates that each domain controller should be setup with a different DNS server as it’s preferred DNS server, and and the loopback address (127.0. 0.1) as it’s alternate DNS server.

Whats the difference between a domain controller and a server?

A Windows Server domain logically groups users, PCs, and other objects in a network, while a domain controller authenticates access requests to the domain’s resources. It also stores information about user accounts and devices and enforces security policies.

Why does a domain controller need DNS?

Does Active Directory use LDAP or Kerberos?

Active Directory is a directory server that uses the LDAP protocol.

How do DNS and DHCP work together?

If configured to make DNS updates, the DHCP server attempts to update DNS with the client’s suggested host name. If the DNS update is successful, the DHCP server returns the requested host name to the client. If the DNS update is not successful, the DHCP server returns a different host name to the client.

Can DHCP server and DNS server be the same?

If your DNS and DHCP services are on the same server, that is not a problem. If these are on different machines, it could be that you have an IP address conflict in which case you must change the IP of one of your servers.

Is DHCP same as DNS?

Domain Name System (DNS) is an Internet service that translates domain names (e.g., its.umich.edu) into IP addresses. Dynamic Host Configuration Protocol (DHCP) is a protocol for automatically assigning IP addresses and other configurations to devices when they connect to a network.

Does a domain controller have to have a static IP?

Domain controllers can be configured to obtain an IP address from DHCP, but it’s best practice to configure a static IP address.

Why are there multiple DNS servers?

The major point in having a secondary DNS server is as backup in the event the primary DNS server handling your domain goes down. In this case, your server would be still up, and so without having a backup, nobody could get to your server possibly costing you lots of lost customers (i.e. REAL MONEY).

Can you have multiple primary DNS servers?

You can have as many Primary DNS zones as you wish in your environment. again, one server can host multiple zones. Or if you wish you can have multiple DNS servers each hosting a primary zone.

Should a DNS server point to itself as primary?

For a DNS server, setting its loopback address as a primary DNS improves its performance and increases its availability. However, for a DC with a DNS role, Microsoft suggests that its primary DNS point to any other DC in the site and secondary DNS point to itself (loopback address).

Who runs the root DNS servers?
