Administrative domain.
A simple 2003 installed server in domain is known as the Member server. When we install AD on it then It becomes Domain Controller.
the centralized directory database in the domain model is NTDS.DIT(directory information tree) but for the local sstem not connected to domain is SAM
, the server hosting the replica of Active Directory database is called Domain Controller. In it's database is all information about all objects, that exist in particular Active Directory domain.
Active Directory
In Windows Server 2008, unlike previous server operating Systems, there is an additional step that needs to be taken before running DCPROMO to promote the server to Domain Controller and installing Active Directory on it. This step is the installation of Active Directory Domain Services (AD-DS) role on the server.(dcpromo ad-ds) The AD-DS role is what enables the server to act as a Domain Controller, but you will still need to run DCPROMO from the run.
Active Directory NC (Naming Context's) * Active Directory consists of three partitions or naming contexts (NC) ** Domain, Configuration and Schema Naming Contexts * Each are replicated independently * An Active Directory forest has single schema and configuration ** Every domain controller (DC) holds a copy of each (schema, configuration NC's) * Forest can have multiple domains ** Every domain controller in a domain holds a copy of the domain NC
No, you do not. You only install Active Directory if the system is going to be a domain controller. If it is a member server or a standalone server Active Directory should not be installed.

The Restartable Active Directory, that allows you to have the ntds.dit in offline mode WITHOUT rebooting the domain controller.
Domain controller is the physical object.

They log onto the domain and not the actual computer.
