Active Directory includes functionality called Sites that allows a domain to define locality for domain controllers and domain-joined clients. The Austin Active Directory defines multiple sites to associate domain controllers with specific locations and networks as well as to isolate certain domain controllers for specific use cases. The Austin Active Directory also defines abbreviated site codes so that the name of a resource can include a shortened reference to an appropriate site.
