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.

In network first server has been install is call domain controller server.. If you wan t to check server is domain controller or, backup domain controller. you can check Run -> cmd -> net accounts If computer role will show PRIMARY it means your domain is PRIYMARY domain controller, if it will be show BACKUP, means you can assume my domain installed in my network is ADC (Additional Domain Controller) Hope you will get benefit..

In AD (OS server 2000,2003 etc) the all the information is stored in NTDS.DIT database if the server is standalone and not connected to any domain then account information is stored in SAM.
Domain controller is the physical object.
No the reason it's called a primary Domain Controller is because it's the one controller that has all the domain names and address for that Domain.
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.

a domain controller (DCO) is a server that responds to security authentication requests (logging in, checking permissions, etc.) within the Windows Server domain
What is the RID Master role? The RID Master is one of the operations master roles that exist in each domain in a forest. It controls the sequence number for the domain controllers within a domain. It provides a unique sequence of RIDs to each domain controller in a domain. When a domain controller creates a new object, the object is assigned a unique security ID consisting of a combination of a domain SID and a RID. The domain SID is a constant ID, whereas the RID is assigned to each object by the domain controller. The domain controller receives the RIDs from the RID Master. When the domain controller has used all the RIDs provided by the RID Master, it requests the RID Master to issue more RIDs for creating additional objects in the domain. When a domain controller exhausts its pool of RIDs, and the RID Master is unavailable, any new object in the domain cannot be created
Metadata cleanup is used to remove the records and data of an crashed Domain Controller or an unsuccesful demotion of a Domain Controller. It is executed on a working domain controller using ntdsutil.
