| Description | The Knowledge Consistency Checker will not construct the topology for partition DC=domain,DC=com because knowledge of the partitions objectGuid has not yet replicated to this domain controller. |
| Event Information | According to Microsoft: CAUSE : This problem occurs when the domain-naming update for the domain has not reached the domain controller that is experiencing the problem. Or, the domain-naming update for a domain that is newly promoted may not have reached any domain controllers outside that domain. You can verify whether the domain-naming update has reached all the domain controllers by modifying the dumpDatabase attribute on the domain controller that is experiencing the problem. RESOLUTION : To resolve this problem, use one of the following methods. Method 1: If one or two domain controllers experience the problem, and other domain controllers in the same domain do not experience the problem, you must demote and then promote the domain controllers that are experiencing the problem. To do this, follow these steps: 1. Log on to the Windows Server 2003-based domain controller by using an account that has domain administrator permissions. 2. Click Start, click Run, type dcpromo, and then click OK. 3. Follow the instructions in the wizard to demote the domain controller. 4. After you demote the domain controller, restart the Windows Server 2003-based computer. 5. Click Start, click Run, type dcpromo, and then click OK. 6. Follow the instructions in the wizard to promote the Windows Server 2003-based domain controller. Method 2: You must rebuild the domain that is mentioned in the event descriptions if one of the following conditions is true: • No domain controllers in the domain received the update. • The domain controllers that reside outside the domain that was reported in the event messages did not receive the update. |
