If the container representing a DNS zone (or subordinate container) becomes conflict mangled, the container representing a more complete copy of a DNS zone can be replaced by container with the same name that's (at first) less complete or even empty.ĭetermine which copy of the zone should remain. And the instance created by the last writer domain controller remains. Specifically, a "*CNF:" string is appended to the DN path of the created object. When the replication of objects causes a name conflict (two objects have the same name within the same container, or have the same container name), the directory automatically renames one of the objects to have a unique name. When two domain controllers create the same object or container inside a replication window, the directory applies conflict resolution logic to determine: With exceptions, Active Directory allows for any domain controller to originate creating an object in a writable directory partition. TechNet: Using DNS aging and scavenging Cause 2: DNS zones are CNF or conflict mangled in Active Directory For example, if these values are both less than 24 hours, then you'll lose DNS records. Verify that the NoRefresh and Refresh intervals are too low. Even Windows-based computers that have statically assigned servers register their records every 24 hours. Scavenging is the most common culprit when DNS records go missing from DNS zones. Resolution Cause 1: DNS scavenging is misconfigured

"Dynamically update DNS A and PTR records for DHCP clients that don't request update"Īffected DNS records include the host "A," host "AAAA," and PTR records."Discard A and PTR records when lease is deleted"."Always dynamically update DNS A and PTR records".The deletion occurs when the client's dynamic lease is transitioned to a reservation, and the following settings are enabled:

It makes the record vulnerable to deletion by a correctly configured DNS Scavenging process.ĭNS records are deleted when a given Windows client dynamic lease is changed to a reservation.ĭNS records that are currently registered by a DHCP-enabled Windows client are deleted by the DHCP server.

Record registration failures make records vulnerable to the scavenging process.ĭNS dynamic update protocol updates for existing records fail. Timing issue caused when you change DNS server IP unless KB2520155 is installed.Ī DNS client's DNS Host record is deleted after you change the DNS server IP address on the same client. They deregister host "A" records during "AAAA" record registration. Windows 7 and Windows Server 2008 R2-based computers which receive DHCP-assigned addresses have Option 81 defined on the DHCP server. It occurs in Windows Vista, Windows Server 2008, Windows 7, or Windows Server 2008 R2.Ī timing bug causes the premature deletion of host "A" records when the DNS Server IP is changed.ĭHCP clients configured with Option 81 deregister host "A" records during host "AAAA" registration. Host "A" record is deleted when the IP address is changed. The bug causes records to be deleted from secondary zones on Windows Server 2008 DNS Servers following zone transfer. Windows Server 2008 zone transfer deletion bug. It modifies the DnsAvoidRegisterRecords registry setting under the hklm\software\policies\microsoft\netlogon\parameters registry subkey.

It was replaced by a different container that may first be empty or contain a subset of the records contained in the previous instance of the zone.ĭnsAvoidRegisterRecord defined in a Group Policy Object (GPO).Ī code defect exists if SRV record registration is excluded by using the DC locator DNS records not registered by the DCs Group Policy setting. The container representing the DNS zone in Active Directory has become CNF or conflict mangled. The Scavenging feature on one or more DNS Servers was configured to have overly aggressive settings and is prematurely deleting DNS records for AD-integrated DNS zones.ĭNS zones are CNF or conflict mangled in Active Directory. Multiple root causes exist, and they're listed in the following table: Cause Successfully registered DNS records are no longer present in a DNS zone.
