Metadata in Active Directory refers to data that describes the properties and characteristics of objects within the directory, such as users, groups, and computers. This includes attributes like user names, security identifiers (SIDS), and permissions, as well as schema information that defines the structure of the data. Metadata is essential for the functioning of Active Directory, enabling efficient organization, retrieval, and management of directory objects. It also plays a crucial role in replication and consistency across domain controllers.
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.
The role of ESE in an active directory is to store and retrieve data through indexed and sequential access.Its the data storage technology from Microsoft.
because this is important
Active Directory is called active bacause it is actively updating it's data through replication from differnt sites and other domain controllers with in the network
Windows 2000 Active Directory data store, the actual database file, is %SystemRoot%\ntds\NTDS.DIT
NTDS.DIT
The schema is the Active Directory component that defines all the objects and attributes that the directory service uses to store data.

The Active Directory configuration partition is a critical component of the Active Directory architecture that stores configuration data for the directory service itself. It contains information about the Active Directory forest, including the schema, replication topology, and services available within the forest. This partition is replicated across all domain controllers in the forest, ensuring that every controller has consistent configuration information. It plays a key role in enabling the functionality and management of Active Directory environments.
Active Directory Recycle Bin helps minimize directory service downtime by enhancing your ability to preserve and restore accidentally deleted Active Directory objects without restoring Active Directory data from backups.By default, Active Directory Recycle Bin in Windows Server 2008 R2 is disabled. To enable Active Directory Recycle Bin, your environment must meet the requirements to completed scenarioused to restore object deleted form AD or restore Multi OUs.
Active Directory Recycle Bin is a feature that helps minimize directory service downtime by enhancing your ability to preserve and restore accidentally deleted Active Directory objects without restoring Active Directory data from backups, restarting Active Directory Domain Services (AD DS), or rebooting domain controllers. When you enable Active Directory Recycle Bin feature, all link-valued and non-link-valued attributes of the deleted Active Directory objects are preserved and the objects are restored in their entirety to the same consistent logical state that they were in immediately before deletion. For example, restored user accounts automatically regain all group memberships and corresponding access rights that they had immediately before deletion, within and across domains. Active Directory Recycle Bin is functional for both AD DS and Active Directory Lightweight Directory Services (AD LDS) environments. Mohannad Hamid
