Directory Services Restore Mode (DSRM)tryrestartable Active Directory feature, which allows you to place the ndts.dit file in a offline mode without rebooting the domain controller outright.
A nonauthoritative restore is the default method for restoring Active Directory. To perform a nonauthoritative restore, you must be able to start the domain controller in Directory Services Restore Mode. After you restore the domain controller from backup, replication partners use the standard replication protocols to update Active Directory and associated information on the restored domain controller. An authoritative restore brings a domain or a container back to the state it was in at the time of backup and overwrites all changes made since the backup. If you do not want to replicate the changes that have been made subsequent to the last backup operation, you must perform an authoritative restore. In this one needs to stop the inbound replication first before performing the An authoritative restore.
Non-authoritative restore is the default method for restoring Active Directory. Non-authoritative restore of SYSVOL When you non-authoritatively restore the SYSVOL, the local copy of SYSVOL on the restored domain controller is compared with that of its replication partners. After the domain controller restarts, it contacts its replication partners, compares SYSVOL information, and replicate the any necessary changes, bringing it up-to-date with the other domain controllers within the domain. Perform a non-authoritative restore of SYSVOL if at least one other functioning domain controller exists in the domain. This is the default method for restoring SYSVOL and occurs automatically if you perform a non-authoritative restore of the Active Directory. If no other functioning domain controller exists in the domain, then perform a primary restore of the SYSVOL. A primary restore builds a new File Replication service (FRS) database by loading the data present under SYSVOL on the local domain controller. This method is the same as a non-authoritative restore, except that the SYSVOL is marked primary.
Domain Controller it is Microsoft Windows Server 2000/2003 directory server that provides access controls over users, accounts, groups, computers and other network resources. Domain Controller authenticate users and maintains directory services and the security database for a domain.

Domain controller is the physical object.
To make a server a domain controller, you typically follow two main steps: first, install the Active Directory Domain Services (AD DS) role on the server using the Server Manager or PowerShell. Next, promote the server to a domain controller by running the Active Directory Domain Services Configuration Wizard, where you'll specify whether to create a new domain in a new forest or add it to an existing domain.
Its similar to a Domain Controller, but it runs teh fuctions for a remote office to provide people / uders access to the Active Directory Domain Services like accesing to their accounts and objects.
The Active Directory database is stored on each domain controller in a file called NTDS.DIT
Domain Controller
Yes its is located but replaced by another Smaller SAM database SAM Accounts on a Windows 2000 Server That Becomes a Domain Controller When you install Active Directory on a computer that is running Windows 2000 Server to create a domain controller, you can either create a new domain or configure the domain controller to contain a copy of an existing domain. In both cases, the existing registry key that contains the SAM database is deleted and is replaced by a new, smaller SAM database. The security principals in this database are used only when the server is started in Directory Services Restore Mode. The disposition of the security principals in the SAM database on the server is different in each case, as follows: If you create an additional domain controller in an existing domain, the security accounts in the existing SAM database on the server are deleted. The accounts from the existing domain are replicated to Active Directory on the new domain controller. If you create a new domain, the security accounts in the existing SAM database are preserved as follows: User accounts become user objects in Active Directory. Local groups in the account domain become group objects in Active Directory. The group type indicates a local group. Built-in local groups become group objects in Active Directory. The group type indicates a built-in local group. These groups retain their constant SIDs and are stored in the Builtin container.
