Mastering Active Directory

Physical components

In the previous section, I explained the logical components of the Active Directory. Now it's time to look into the physical components. Even though logical and physical components are equally important in the Active Directory Domain Service design, they are independent. Replication is the core feature of the Active Directory Domain Services. If a system has multiple domain controllers, changes made in one domain controller should be replicated to others. Physical component placement can affect Active Directory replications in certain ways. Logically, components can be easily rearranged compared to physical components.
