When a target domain controller receiving Windows Server 2003 with a specific Service Pack (SP1) receives event ID 2088 in its directory service event log, it tries to use a unique global identifier (GUID) in the alias (CNAME) – delete Resource record to populate the IP address of the source domain controller. However, the target controller’s domain tried a variety of name resolution methods and got the fully qualified website name (FQDN) or NetBIOS domain name of the source controller. Although replication is successful, you still need to diagnose and fix the root cause of the Domain Name System (DNS) problem.

You must fix this DNS location error immediately so that this domain controller can use DNS very well to resolve the IP address of the resource domain controller.
NOTE. By default, up to 10 DNS errors are suggested in a given 12 hour period, possibly even if more than 10 errors occur. To log all individual error events, correct the following value in the diagnostic register in direction 1:
If the source domain controller does not have additional functionality or isThe operating system started to reinstall on another computerTarget NTDSDSA name or GUID, remove itNtdsutil with .exe metadata. Further actions are describedFor more information, see MSKB article 216498.
Confirm that the domain controlled source is running Active Directory and offered on the network using "net look at" or "ping". Enter.
Verify that the source domain controller also uses a valid DNS server for DNS services and that the host and cname records of the source website controller are registered for it with DCDIAG Enhanced DNS. EXE is available at https://www.microsoft.com/dns

You plugged in a controller this morning that crashed in 2003 and is no longer coming back. It was a special "fallback" controller, so I used ntdsutil to remove it after creating another to replace it. Everything went smoothly. I immediately restarted the fsmo domain controller and got the following error message. Because of this, only you know that DNS is built into AD. FSMO installed DNS and new DC "Backup".
Event type: warning Event Source: NTDS Replication Event Category: DS RPC Client Event ID: 2088 Date: 12/07/2010Time: 11:20:20 User: NT AUTHORITIES ANONYMOUS REGISTRATION Computer: DC-FSMO Description: Active Directory was unable to use DNS to resolve the IP address of the source controller region specified below. To maintain consistency between security groups, group policies, users and individuals and their passwords, Active Directory has been successfully replicated using NetBIOS or a name fully recognized by the computer from the original domain controller.
Invalid DNS configuration can have other consequences for related operations on member computers, domain controllers, or application servers in these Active Directory forests, such as logon authentication or access to Internet resources.
You must fix this DNS configuration error immediately so that this domain can use DNS for controlled resolution of the source domain controller's IP address.

NOTE. By default, only 10 DNS failures are displayed for almost 12 hours if more than 10 failures occur. To log nearly all error events, set the following diagnostic register to 1:

User response:
1) If the original domain controller stopped working or system operations were reinstalled with a different computer name or NTDDSSA object GUID, remove the original site controller metadata using ntdsutil .exe following the precautions in MSKB article 216498.
2) Make sure the original domain controller is active and the directory can be accessed over the network by typing "net view " or "ping ".
3) Verify that the source domain is an operator using a valid DNS server for DNS services, and that the host record and CNAME record of the source domain controller are correctly registeredThey are created using the extended version of DNS. : //www.microsoft.com/dns

4) Verify that this target domain statement is using a valid DNS server for DNS services by running the extended DNS command DCDIAG.EXE on the target domain's Xbox 360 as a controller.
