RepAdmin Commands (2024)

FAQs

What is the repadmin command? ›

Repadmin is a command-line tool in Windows operating systems used to manage and troubleshoot Active Directory replication. It's particularly useful for administrators to monitor and diagnose replication issues in a Windows domain environment.

How do I check my AD replication status? Running the repadmin /showrepl can help you view the replication status. If you would like an overall replication health summary, the command repadmin /replsummary should help.

Repadmin /kcc <DCNAME> is the command to force KCC to run. However it won't create a new connection if the other one is still in place. Replace <DCNAME> with the name of the domain controller that serves as the ISTG for the site.

To force Active Directory replication run 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 example, if DC2 is out of Sync, run the command on DC2.

To use Repadmin.exe, you must run the ntdsutil command from an elevated command prompt. To open an elevated command prompt, click Start, right-click Command Prompt, and then click Run as administrator. You can use Repadmin.exe to view the replication topology, as seen from the perspective of each domain controller.

Open a Windows command prompt. Check the status of the last replication that involved the restored DC by issuing the repadmin /showrepl command¹. This command shows the replication partners for each directory partition on the DC and the status of the last replication.

If you have replication issues, then monitoring the queue is a good way to check if your domain is healthy or not. To view the queue we can use the following command: repadmin /queue # Result Repadmin: running command /queue against full DC localhost Queue contains 0 items.

In a windows domain you can run the "repadmin /showrepl" command to view replication health in your domain. You can also look at DNS Event Viewer for issues with replication. Monitoring the replication status requires regular checks to ensure that DNS records are replicating as expected between servers.

In the System Management Settings section, click Active Directory Domain Manager. Select the Action check box for the domain you wish to check, right-click the selection, and then click Properties. Click the Details tab. The Active Directory Synchronization Report appears.

To check NTDS objects for an Active Directory domain controller, open the Active Directory Sites and Services snap-in, and then expand a domain controller for which you want to check the NTDS object as shown in the red square of the screenshot.

How to check KCC status in Active Directory? ›

A server running Active Directory is part of a distributed system that performs replication. The Knowledge Consistency Checker (KCC) is a component that reduces the administrative burden of maintaining a functioning replication topology.

Displays the replication status when the specified domain controller last attempted to perform inbound replication of Active Directory partitions. The repadmin /showrepl command helps you understand the replication topology and replication failures.

The largest replication delta means the longest time gap that occurred between replications for that domain controller. You can also see in the output if any replication activities failed. You can get more detail of the replication activity of each domain controller with the command repadmin /showrepl.

The showrepl (or showreps ) command of repadmin reports the replication status for each source DC from which the destination DC has an inbound connection object.

Displays the replication status when the specified domain controller last attempted to perform inbound replication of Active Directory partitions. The repadmin /showrepl command helps you understand the replication topology and replication failures.
