Mastering Active Directory - Second Edition

AD replication

Healthy replication is a must for an AD environment. AD uses a multi-master database, so every domain controller in the environment should be aware of every change in an AD database. As well as this, they should also know about changes in group policies, startup scripts, preference setting, and more. When it comes to replication, it is not only the replication service that is responsible for it. There should be an uninterrupted communication between domain controllers.

This communication media can be copper cables, fiber cables, or even a Software-Defined Network (SDN). In this section, we are going to look at how we can use the AD-integrated features to maintain healthy replication.
