Your company has a branch officethat is configured as a separate Active Directory siteand has an Active
Directory domain controller.
The Active Directory site requiresa local Global Catalog serverto support a new application.

What Is the Global Catalog?
The global catalog is a distributed data repositorythat contains a searchable, partial representationof every
object in every domain in a multidomain Active Directory Domain Services (AD DS) forest. The global catalog is
stored on domain controllers that have been designated as global catalog servers and is distributed through
multimaster replication. Searches that are directedto the global catalog are faster because they do not involve
referrals to different domain controllers.
In addition to configuration and schema directory partition replicas, every domain controller in a forest stores a
full, writable replica of a single domain directorypartition. Therefore, a domain controller can locate only the
objects in its domain. Locating an object in a different domain would require the user or application to provide
the domain of the requested object.
The global catalog provides the ability to locate objects from any domain without having to know the domain
name. A global catalog server is a domain controller that, in addition to its full, writable domain directory
partition replica, also stores a partial, read-onlyreplica of all other domain directory partitions in the forest. The
additional domain directory partitions are partial because only a limited set of attributes is included for each
object. By including only the attributes that are most used for searching, every object in every domain in even
the largest forest can be represented in the database of a single global catalog server.
Note:A global catalog server can also store a full, writable replica of an application directory partition, but
objects in application directory partitions are notreplicated to the global catalog as partial, read-only directory
partitions.
The global catalog is built and updated automatically by the AD DS replication system. The attributes that are
replicated to the global catalog are identified in the schema as the partial attribute set (PAS) and are defined by
default by Microsoft. However, to optimize searching, you can edit the schema by adding or removing attributes
that are stored in the global catalog.
In Windows 2000 Server environments, any change to the PAS results in full synchronization (update of all
attributes) of the global catalog. Later versions of Windows Server reduce the impact of updating the global
catalog by replicating only the attributes that change.
In a single-domain forest, a global catalog server stores a full, writable replica of the domain and does not store
any partial replica. A global catalog server in a single-domain forest functions in the same manner asa nonglobal-catalog server except for the processing of forest-wide searches.
