(1) A ticket that a principal passes to the ticket-granting server when a service ticket is requested. The ticket-granting service uses the ticket-granting ticket to verify that the principal has authenticated to the authentication server before it grants the request for the service ticket.
(2) A ticket that allows access to the ticket granting service on the key distribution center (KDC). Ticket granting tickets are passed to the principal by the KDC after the principal has completed a successful request. In a Windows 2000 environment, a user logs on to the network and the KDC will verify the principal's name and encrypted password and then send a ticket granting ticket to the user.
