Active Administrator 8.7 - Web Console User Guide

Infrastructure master not responding

Indicates that the infrastructure operations master is not responding within the configured threshold.

This error can occur if any of the following occurs:

Infrastructure operations master inconsistent

Indicates that the infrastructure operations master is not consistent among all domain controllers in the domain.

The infrastructure operations master is contained in the fSMORoleOwner property of the infrastructure object contained by each domain object. Every domain controller in the domain has a copy of the infrastructure operations master.

Active Directory® objects can contain links to other objects in the directory. Active Directory keeps these links up-to-date even if the linked-to object is moved to another container or is renamed. This update cannot happen if the linked-to object is in another domain.

If the infrastructure operations master is inconsistent, it is possible that two copies will run simultaneously on two different domain controllers, with potentially disastrous consequences.

The Infrastructure operations master can become inconsistent because an administrator used NTDSUTIL.EXE to move the Operations Master when there was incomplete connectivity to all domain controllers in the domain. It can also occur because of replication errors.

Wait to see if the error clears itself. If an administrator has moved an operations master to another domain controller, replication to all domain controllers in the domain can take some time.

If you have waited long enough for replication to have occurred to all domain controllers in the domain, contact your Microsoft Windows support representative.

Objects exist in the Lost and Found

Generated when Active Directory Health Analyzer discovers objects in the Lost And Found container of a naming context.

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 DSA will place objects in the Lost And Found container as part of its normal operation. However, several Lost And Found objects may indicate a replication problem, or at least the deletion of a container that should not have been deleted.

Inspect the objects in the Lost And Found container of the replica using an appropriate utility. Move the objects to an appropriate container or delete them from the Lost And Found container.

PDC master not responding

Indicates that the PDC (primary domain controller) operations master is not responding within the configured threshold.

This error can occur if any of the following occurs:
