The global catalog is the central repository of information about objects in a tree or forest and is created automatically on the initial domain controller in the first domain in the forest, known as the global catalog server. A global catalog server is a domain controller that stores a full copy of all objects in the directory for its host domain and a partial copy of all objects for all other domains in the forest.

Universal group membership caching, a new feature in the Windows Server 2003 operating system, allows a site that does not contain a global catalog server to be configured to cache universal group memberships for users who log on to the domain controller in the site. The universal group membership caching feature must be set for each site and requires a domain controller to run a Windows Server 2003 operating system.

For optimum network response time and application availability, designate at least one domain controller in each site as the global catalog server. To optimize replication in a multiple site environment, you might need to consider adding global catalogs for specific sites.
