Configuring Dynamic Updates
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
Dynamic update enables Domain Name System (DNS) client computers to register and dynamically update their resource records with a DNS server whenever changes occur. This reduces the need for manual administration of zone records, especially for clients that frequently move or change locations and use Dynamic Host Configuration Protocol (DHCP) to obtain an Internet Protocol (IP) address.
The DNS Server service allows dynamic update to be enabled or disabled on a per-zone basis at each server that is configured to load either a standard primary or directory-integrated zone. By default, the DNS Client service dynamically updates host address (A) resource records in DNS when it is configured for TCP/IP.
Secure dynamic update is available only for zones that are integrated into Active Directory. After you directory-integrate a zone, access control list (ACL) editing features are available in the DNS snap-in. You can use these features to add or remove users or groups from the ACL for a specified zone or resource record.
For more information about planning DNS zones and dynamic updates, see Deploying Domain Name System (DNS) on the Microsoft Web site (https://go.microsoft.com/fwlink/?LinkId=45677).
You can use this task to enable or disable dynamic updates or to allow only secure dynamic updates.
