Active Directory Interview Question:

Define the global catalog key directory roles?

Submitted by: Administrator

When a user logs on to the network, the global catalog provides universal group membership information for the account sending the logon request to the domain controller. If there is only one domain controller in the domain, the domain controller and the global catalog are the same server. If there are multiple domain controllers in the network, the global catalog is hosted on the domain controller configured as such. If a global catalog is not available when a user initiates a network logon process, the user is only able to log on to the local computer.
