Active Directory Diagrams

The vector stencils library "Active Directory Sites and Services" contains 12 symbol icons of Active Directory Sites and Services design elements for drawing high-level network topology plan diagrams.
"Active Directory® Sites and Services is a Microsoft Management Console (MMC) snap-in that you can use to administer the replication of directory data among all sites in an Active Directory Domain Services (AD DS) forest. This snap-in also provides a view of the service-specific objects that are published in AD DS. ...
Administrators who are responsible for forest-wide service administration can use Active Directory Sites and Services to manage the intersite replication topology for the forest. Administrators who are responsible for application services can be delegated responsibility for the service containers into which application-specific objects are published.
When you add the Active Directory Domain Services server role to a server, Active Directory Sites and Services is added to the Administrative Tools menu." [technet.microsoft.com/ en-us/ library/ cc730868.aspx]
The symbols example "Active Directory Sites and Services - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Active Directory Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

The shapes example "Design elements - Active Directory Sites and Services" for the ConceptDraw PRO diagramming and vector drawing software is icluded in the Active Directory Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

This example was drawn on the base of the Figure 2 illustrating the "Active Directory FAQ" from the website "Information Management Systems & Services" (IMSS) of the California Institute of Technology (Caltech) campus. [imss.caltech.edu/ node/ 412]
"By using the Active Directory® Domain Services (AD DS) server role, you can create a scalable, secure, and manageable infrastructure for user and resource management, and you can provide support for directory-enabled applications, such as Microsoft® Exchange Server. ...
AD DS provides a distributed database that stores and manages information about network resources and application-specific data from directory-enabled applications. Administrators can use AD DS to organize elements of a network, such as users, computers, and other devices, into a hierarchical containment structure. The hierarchical containment structure includes the Active Directory forest, domains in the forest, and organizational units (OUs) in each domain. A server that is running AD DS is called a domain controller." [technet.microsoft.com/ en-us/ library/ 9a5cba91-7153-4265-adda-c70df2321982]

This AD diagram example was redesigned from the picture "Site links" from the book "Active Directory for Dummies".
"Site links represent the Active Directory replication paths between sites.
These paths are manually defined so that the designer has control over which network links the replication traffic occurs on. These site links also control how clients are directed to domain controllers when there’s no DC in the client’s local site. Each site link has the following attributes:
(1) Connected sites: A site link is defined by the sites to which it connects. A site link can connect two or more sites together.
(2) Network transport: Site links support replication communication over IP-based RPCs or with the Simple Mail Transport Protocol (SMTP). You normally want to use RPC whenever possible, but you can use SMTP when the sites you’re linking don’t support RPC.
(3) Cost: Each site link has a cost associated with it. Costs are used to assign preferences to links that determine which link should be followed when multiple link paths are available between sites. The cost represents what it “costs” to use this site link relative to the other site links and affects replication traffic as well as how users are assigned a domain controller. Links with lower cost values have preference over links with higher cost values. Cost values range from 1–32,767; the default being 100.
(4) Frequency: The frequency value defines how often a replication occurs
when using this site link (the replication latency). You can configure the time between replications from a minimum of 15 minutes to a maximum of 10,080 minutes (one week). The default frequency is 180 minutes.
(5) Schedule: The schedule dictates when this link is active and available for replication between the sites. The schedule can also control which days of the week the link is available. Normally, the schedule is set so that the link is available 24 hours a day, but you can set up different schedules on a per-day-of-the-week basis.
By creating a site link, you enable two or more sites to be connected and to share the same site link attributes (transport, cost, frequency, and schedule). By default, site links create transitive connectivity between sites.
If you create a site link between sites A and B and another site link between
sites B and C, an automatic connection (known as a site link bridge) is created between sites A and C..." [Steve Clines and Marcia Loughry, Active Directory® For Dummies®, 2nd Edition. 2008]

This AD diagram example was redesigned from the picture "Single root domain with a structured OU model" from the book "Active Directory for Dummies".
"A domain is the cornerstone that you lay whenever you create trees and forests. Regardless of whether you design a tree or a forest, the starting point is always the root domain. The root domain is the first domain that you create in your AD structure, and it sits at the top of your diagram.
The root domain of your tree, similar to any other domain, is a grouping of
resources built on the following components:
(1) Domain controllers.
(2) Security policies. ...
For many small and medium-sized companies, a single root domain with a
structured OU (organizational unit) model... provides sufficient flexibility for an AD tree. ...
However, larger companies, companies with complex organization charts, and
companies with multiple sites often find that a single domain isn’t suitable." [Steve Clines and Marcia Loughry, Active Directory® For Dummies®, 2nd Edition. 2008]
