Repadmin is the ultimate replication diagnostic tool. In addition to checking the health of your domain controllers, it can also be used to force replication and pin point errors. Active Directory replication is a critical service that keeps changes synchronized with other domain controllers in the forest.


Moreover, how do I know if AD replication is working?

Steps to check AD Replication in Windows Server 2012 R2 through Command Prompt (Repadmin) 1. The first command that we are run is “Repadmin /replsummary” to check the current replication health between the domain controllers.

Furthermore, how can I tell if a domain controller is synced?
  1. Step 1 - Check the replication health. Run the following command :
  2. Step 2 - Check the inbound replication requests that are queued.
  3. Step 3 - Check the replication status.
  4. Step 4 - Synchronize replication between replication partners.
  5. Step 5 - Force the KCC to recalculate the topology.
  6. Step 6 - Force replication.

In this manner, how do you force replication in Repadmin?

In order to force Active Directory replication, issue the command 'repadmin /syncall /AeD' on the domain controller. Run this command on the domain controller in which you wish to update the Active Directory database for. For example if DC2 is out of Sync, run the command on DC2.

How do I fix Active Directory replication issues?

  1. Force AD DS removal in Directory Services Restore Mode (DSRM), clean up server metadata, and then reinstall AD DS.
