Event ID 4018 — DNS Server Active Directory Integration

Applies To: Windows Server 2008

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.

Free memory or other system resources

Close any unnecessary applications or services, and then try the operation again.

If the operation fails again, restart the computer to free any memory or other system resources that have been allocated by programs without being released. Use Server Manager to ensure that the DNS Server service has started.

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

To restart the computer:

  • On the DNS server, click Start, click the arrow next to the Lock button, and then click Restart.

To ensure that the DNS Server service has started:

  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, and then click DNS Server.

The System Services list shows the state of the DNS Server service.

If the problem persists, one or more applications running on the server might be causing memory problems.


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.
