JSI Tip 9952. Events 1481 and 1084 are logged in the Directory Service log on a Windows Server 2003 domain controller?

Your Windows Server 2003 Directory Service event log contains entries similar to:

Event Type:	Error
Event Source:	NTDS Replication
Event Category:	Internal Processing
Event ID:	1481
Description:    Internal error: The operation on the object failed.

Additional Data
Error value: 5 000020D9: SvcErr: string varies, problem 5001 (BUSY), data


Event Type:	Error
Event Source:	NTDS Replication
Event Category:	Replication
Event ID:	1084
Description:
Internal event: Active Directory could not update the following object with changes received
                from the following source domain controller. This is because an error occurred
                during the application of the changes to Active Directory on the domain controller.

Object:
object DN
Object GUID: ef688125-9639-4238-88db-68b663844609
Source domain controller: guid-based DC name
                          Synchronization of the local domain controller with the source domain controller is blocked
                          until this update problem is corrected.

This operation will be tried again at the next scheduled replication.

User Action
Restart the local domain controller if this condition appears to be related to low system resources
 (for example, low physical or virtual memory).

Additional Data
Error value: 8409 A database error has occurred.

This behavior occurs when an Active Directory object that is currently being used is deleted from the Active Directory directory service.

NOTE: The replication engine will attempt to move the object to the Deleted Objects container later.
