Global catalog verification
Applies To: Windows Server 2008 R2
Domain controllers on a network must contact global catalog servers to perform certain functions. For example, if an administrator adds a user from another domain in the forest to a domain local group in the local domain, a global catalog server is used to obtain the appropriate information to be added for the user. If the local domain controller is not a global catalog server, it locates another domain controller that is hosting the global catalog to obtain the appropriate information.
