Event ID 1699 is logged many times and fills the Directory Service event log of a Windows Server 2008-based writable domain controller

Consider the following scenario:

• You have a Windows Server 2008-based writable domain controller and a Windows Server 2008-based read-only domain controller (RODC). Some client computers that exist in one site belong to the same domain.
• Some users use a domain account to log on to the domain from a client computer that is in the site.

In this scenario, Event ID 1699 is logged many times in the Directory Service event log of the writable domain controller. These events resemble the following event:

Source: NTDS Replication
Date: Date
Event ID: 1699
Level: Error
Keywords: Classic
User: user name
Computer: computer name
Description:
This directory service failed to retrieve the changes requested for the following directory partition. As a result, it was unable to send change requests to the directory service at the following network address.

Directory partition: Distinguished Name (DN)
Network address: address

Additional Data
Error value: 8453 Replication access was denied.

Sometimes, Event ID 2041 may also be logged. The event that is logged resembles the following event:

Event Type: Information
Event Source: NTDS General
Event Category: Internal Processing
Event ID: 2041
Date: date
Time: time
User: N/A
Computer: computer name
Description:
Duplicate event log entries were suppressed.
See the previous event log entry for details. An entry is considered a duplicate if the event code and all of its insertion parameters are identical. The time period for this run of duplicates is from the time of the previous event to the time of this event.

Event Code: c00006a3
Number of duplicate entries: 1

These events fill the Directory Service event log and prevent administrators from troubleshooting issues according to the event logs.

When a Windows Server 2008 RODC tries to cache the password of a principal, a writable domain controller performs a check to determine whether this operation is permitted. If this operation is not permitted, an error code is returned. This is expected behavior. However, Event 1699 may incorrectly be logged when the error code is returned.

A hotfix is available to resolve this issue. After you install this hotfix, the server does not log Event ID 1699 in the scenario that is mentioned in the "Cause" section. In other scenarios, the event is still logged.

Note This hotfix is already incorporated on Windows Server 2008 R2 full DCs. The fix is not required on Windows Server 2008 R2 full DCs.
