Healthy replication is the key to the healthy Active Directory environment. Active Directory uses multi-master database, so every domain controller in the environment should be aware of any changes made to any of the Active Directory databases. It is not only that, it should also know about changes in group policies, startup scripts, preferences settings, and so on, which will also be saved in the SYSVOL folders. When it comes to replication, it is not only the replication service responsible for it. There should be an uninterrupted communication between domain controllers. This communication media can be copper cables, fiber cables, or even via a Software Defined Network (SDN). In this section, we are going to look at how we can use the Active Directory integrated features to maintain a healthy replication.
