you can type dcpromo and follows instcution on screen to remove AD
You run the 'dcpromo' command to remove active directory and demote a domain controller to a member server. To remove AD completely you would have to do this process on all domain controllers.
dcpromo is command u have to write it in Run to create a new domain controller and create active directory
Domain controller is the physical object.
The dcpromo command is used to promote a Windows Server to a domain controller in Active Directory. When executed, it initiates a wizard that guides the administrator through the process of configuring the server, including setting up a new domain, joining an existing domain, or creating a new forest. The command handles the necessary installations, configurations, and replication settings required for the server to function as a domain controller. Note that in newer versions of Windows Server, this command is replaced by the Server Manager interface for Active Directory Domain Services (AD DS) installation.
The Active Directory database is stored on each domain controller in a file called NTDS.DIT
Domain Controller
The Restartable Active Directory, that allows you to have the ntds.dit in offline mode WITHOUT rebooting the domain controller.
In Windows Server 2011 it is called Active Directory.
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.
NTDS.DIT
, 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.
