The Active Administrator® Foundation Service (AFS) periodically queries to find the response time of the infrastructure operations master. If the response time is above the threshold, an alert is generated.
This error can occur if any of the following occurs:
• |
• |
Active Directory® on the domain controller has failed in some way. |
• |
Make sure the indicated domain controller actually exists. If it does not exist, run NTDSUTIL and select the metadata cleanup option to clean up the erroneous objects in the directory. |
• |
Check the LDAP response time for the domain controller on the Active Directory tab in Active Directory Health Analyzer. If it is too high, you may need to add another domain controller for the same domain in the same site. |

Required permissions: Domain user privilege is required and the target server must have WMI remote access enabled. The user must be a member of the Distributed COM Users group. |
Since Active Directory®, by default, sets all the clocks on all of the domain controllers in the forest from the PDC Role Owner of the root domain, it is recommended that the domain controller be configured to synchronize its time with an external time source. This alert is active if the root domain PDC Owner is not so configured.

The Active Administrator® Foundation Service (AFS) periodically checks to see if there are any objects in the Lost And Found container in the domain. If there are, the DC Agent will issue an alert.
During the replication process, Active Directory® may encounter orphaned objects, which are objects that have no parent container. For example, a user deletes container X on domain controller A, and another user modifies object Y contained in container X on domain controller B. During replication, domain controller A will receive an update operation for an object that has no container because container X was deleted. In this case, the directory system agent (DSA) on domain controller A puts the object in the Lost And Found container.

The Active Administrator® Foundation Service (AFS) periodically checks the consistency of the domain PDC operations master value across all of the domain controllers in the domain. If any of the domain controllers has a differing value for the domain PDC operations master, an alert is issued.
If alert does not clear, contact your Microsoft Windows support representative.
