There are a ton of things that can cause replication issues from wrong configurations to hardware failures.  That is why there are different commands to run to see what errors are thrown.

Hi Member_2_7969835,

yes, that's typical for a VM that is not always on.

GUI  Method:
You can go to the Active Directory Sites and Services console, and then expand the AD sites down to the server, and then under the server click on NTDS settings.

On the right console, right click on the connections and select Replicate Now. You can do it for all AD domain controllers and force it to replicate.

Command Line method:

Below is a command to replicate from a specified DC to all other DC’s.

Repadmin /syncall DC_name /APed

Open in new window
