You can configure the DNS Server service to use Active Directory Domain Services (AD DS) to store zone data. This makes it possible for the DNS server to rely on directory replication, which enhances security, reliability, and ease of administration.

Event Details

Troubleshoot AD DS and reload the zone

The DNS Server service relies on Active Directory Domain Services (AD DS) to store and retrieve information for AD DS-integrated zones. This error indicates that AD DS is not responding to requests from the DNS Server service. Ensure that AD DS is functioning properly, troubleshoot any problems, and then reload the zone.

For information about troubleshooting AD DS, see Active Directory Troubleshooting Topics (http://go.microsoft.com/fwlink/?LinkId=95789).

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To reload a zone:

  1. On the DNS server, start Server Manager. To start Server Manager, click Start, click Administrative Tools, and then click Server Manager.
  2. In the console tree, expand Roles, expand DNS Server, and then expand DNS.
  3. Expand the DNS server, and then expand the folder containing the zone that you want to reload.
  4. Right-click the zone, and then click Reload.

Verify

Ensure that Event IDs 4523 and 4524 are being logged and that no events in the range 4000 to 4019 appear in the Domain Name System (DNS) event log.
