Actually it's the 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.

WHOIS
, 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.

Conserved Domain Database was created in 2003.
a domain as "a single security boundary of a Windows NT-based computer network. Active Directory is made up of one or more domains. On a standalone workstation, the domain is the computer itself. A domain can span more than one physical location. Every domain has its own security policies and security relationships with other domains. When multiple domains are connected by trust relationships and share a common schema, configuration, and global catalog, they constitute a domain tree. Multiple domain trees can be connected together to create a forest." Domain A Windows domain is a collection of security principals that share a central directory database. This central database (known as Active Directory starting with Windows 2000,[1] Active Directory Domain Services in Windows Server 2008 and Server 2008 R2, also referred to as NT Directory Services on Windows NT operating systems, or NTDS) contains the user accounts and security information for the resources in that domain. Each person who uses computers within a domain receives his or her own unique account, or user name. This account can then be assigned access to resources within the domain. In a domain, the directory resides on computers that are configured as "domain controllers." A domain controller is a server that manages all security-related aspects between user and domain interactions, centralizing security and administration. A Windows Server domain is generally suited for businesses and/or organizations when more than 10 PCs are in use.
