Active Directory Domain Topology

An Active Directory domain topology diagram shows the Windows infrastructure that supports identity and access. It puts domain controllers and DNS services beside the switches, servers, and user devices that rely on them. This makes it useful for an operations handoff, a security review, or a change plan. Start with the domain controllers, then add core connectivity, file services, administrative devices, and the client network. Label a controller with its additional roles, such as DNS, so readers can understand what remains available when a server is offline. Keep organizational units and policy links in a separate logical view when they would make this physical topology hard to read.

Qué hay en este dibujo

Lee las decisiones que hay detrás.

01Two domain controllers

Redundant directory and DNS services reduce a single point of failure.

02Core switch

The shared connection point makes the server and user network clear.

03Separate admin workstation

Privileged access is shown apart from ordinary staff devices.

Use this view when the physical and service relationships around a single AD domain matter more than object-level detail.
