Event ID 4000 — 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.
|Product:||Windows Operating System|
|Message:||The DNS server was unable to open Active Directory. This DNS server is configured to obtain and use information from the directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and reload the zone. The event data is the error code.|
Troubleshoot AD DS and restart the DNS Server service
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 restart the DNS Server service.
For information about troubleshooting AD DS, see Active Directory Troubleshooting Topics (http://go.microsoft.com/fwlink/?LinkId=95789).
