If you use this functionality, you can reduce the requirement for manual administration of zone records, especially for clients that frequently move and use Dynamic Host Configuration Protocol DHCP to obtain an IP address.
Windows provides support for the dynamic update functionality as described in Request for Comments RFC For DNS servers, the DNS service permits you to enable or to disable the DNS update functionality on a per-zone basis at each server that is configured to load either a standard primary or directory-integrated zone. When you use this functionality, you improve DNS administration by reducing the time that it requires to manually manage zone records.
Every Active Directory-integrated zone is replicated among all domain controllers in the Active Directory domain. All DNS servers that are running on these domain controllers can act as primary servers for the zone and accept dynamic updates. Active Directory replicates on a per-property basis and propagates only relevant changes. The DNS Server service can scan and remove records that are no longer required. When you enable this feature, you can prevent outdated records from remaining in DNS.
You can configure Active Directory-integrated zones for secure dynamic updates so that only authorized users can make changes to a zone or to a record. By default, all computer register records are based on the full computer name. The primary full computer name is a fully qualified domain name FQDN. Additionally, the primary full computer name is the primary DNS suffix of the computer that is appended to the computer name. This includes connections that are not configured to use DHCP.
By default, Windows registers A and PTR resource records every 24 hours regardless of the computer's role. Dynamic updates are typically requested when either a DNS name or an IP address changes on the computer. For example, a client named "oldhost" is first configured in system properties to have the following names: Computer name: oldhost DNS domain name of computer: example.
In this example, no connection-specific DNS domain names are configured for the computer. If you rename the computer from "oldhost" to "newhost", the following name changes occur: Computer name: newhost DNS domain name of computer: example.
After the name change is applied in System Properties , Windows prompts you to restart the computer. The client computer uses the currently configured FQDN of the computer, such as " newhost.
For standard primary zones, the primary server, or owner, that is returned in the SOA query response is fixed and static. The primary server name always matches the exact DNS name as that name is displayed in the SOA resource record that is stored with the zone.
However, if the zone that is being updated is directory-integrated, any DNS server that is loading the zone can respond and dynamically insert its own name as the primary server of the zone in the SOA query response.
The client processes the SOA query response for its name to determine the IP address of the DNS server that is authorized as the primary server for accepting its name. If it is required, the client performs the following steps to contact and dynamically update its primary server:.
The client sends a dynamic update request to the primary server that is determined in the SOA query response. If this update fails, the client next sends an NS-type query for the zone name that is specified in the SOA record. When the client receives a response to this query, the client sends an SOA query to the first DNS server that is listed in the response.
