What is Drsuapi protocol?

For keeping an environment with more than one DC consistent, it is necessary to have the AD objects replicated through those DCs. Most of the replication related tasks are specified on the Directory Replication Service (DRS) Remote Protocol. The Microsoft API which implements such protocol is called DRSUAPI.

How do you fix replication problems?

If AD DS cannot be removed normally while the server is connected to the network, use one of the following methods to resolve the problem:

1. Force AD DS removal in Directory Services Restore Mode (DSRM), clean up server metadata, and then reinstall AD DS.
2. Reinstall the operating system, and rebuild the domain controller.

What does repadmin Replsummary do?

The Repadmin /Replsummary command provides an active directory replication summary. In other words, Active Directory updates can be written to any domain controller (with read-only domain controllers being the notable exception). Those updates are then replicated to the other domain controllers in the domain.

How do I check my ad health status?

How to check the health of your Active Directory

1. Make sure that domain controllers are in sync and that replication is ongoing.
2. Make sure that all the dependency services are running properly.
3. Use the Domain Controller Diagnostic tool (DCDiag) to check various aspects of a domain controller.
4. Detect unsecure LDAP binds.

How do you check AD replication time?

Checking AD Replication Using Repadmin

1. To quickly check the status of replication on a specific domain controller, run the command: repadmin /replsummary DC1.
2. Hint.
3. CALLBACK MESSAGE: SyncAll Finished.
4. In our article, you can find more details on the repadmin.
5. No replication errors found for this DC (FailureCount : 0).

What is DC sync?

DCSync is a late-stage kill chain attack that allows an attacker to simulate the behavior of Domain Controller (DC) in order to retrieve password data via domain replication.

What is directory replication service?

What to do if Active Directory replication fails?

Code defects in the ADREPLSTATUS tool can typically be resolved relatively quickly. Tool failures due to external causes may take longer, unless a workaround can be found. The ADREPLSTATUS team can’t fix Active Directory replication errors that are identified by the ADREPLSTATUS tool. Contact your support provider to fix the issue.
