RODC denied password replication policy inconsistent

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
Required permissions: Domain user privilege is required.

The msDS-NeverRevealGroup property contains a list of groups (Deny List) whose credentials will be replicated to the given RODC. It is recommended that each RODC in a given naming context have the same groups in its msDS-NeverRevealGroup property. To facilitate the comparison of the lists of groups among a number of RODCs the user selects an RODC as the authoritative source for the msDS‑NeverRevealGroup in a given naming context. The Active Administrator® Foundation Service (AFS) compares all other RODCs in the domain to the authoritative list.

Compare the msDS-NeverRevealGroup attribute of the authoritative RODC to that of the inconsistent RODC, and modify the msDS-everRevealGroup on the inconsistent server to match the authority.

Inter-site replication manager

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
Required permissions: Domain user privilege is required.
Description

Active Directory® allows administrators to configure preferred bridgehead servers for each site. Sometimes connection objects are created manually to solve a quick problem, but they are never removed. If these manually-created links are actively replicating, undesirable results may occur.

If any server other then the preferred bridgehead server(s) has a connection object that handles intersite replication, this alert will be triggered.

If no server if configured as the preferred bridgehead server, this alert is never triggered because the Knowledge Consistency Checker (KCC) is handling all topology replication.

Resolution

It is possible that this is a transient issue caused by Active Directory replication delays associated with updating File Replication service (FRS) configuration objects. If file replication does not take place after an appropriate waiting time, which could be several hours if cross-site Active Directory replication is required, you must manually reset the preferred bridgehead server.

Inter-site replication topology generation disabled

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
Required permissions: Domain user privilege is required.
Description

The Active Administrator® Foundation Service (AFS) periodically checks the Knowledge Consistency Checker (KCC) configuration for each site and alerts when the replication topology generation functionality of the KCC has been explicitly disabled. While disabling the KCC is a valid administrator action, it can result in poorly-tuned replication topologies.

Resolution

Clear the fifth bit (16) of the <Root Domain>\Configuration\Sites\<Site name>\NTDS Site Settings\options value to re-enable inter-site topology generation.
