Kerberos Kerberos is a secure method for authenticating a request for
a service in a network. Kerberos lets a user request an
encrypted “ticket” from an authentication process that can
then be used to request a service from a server. The user
credentials are always encrypted before they are
transmitted over the network.
In Windows 2000/XP, the domain controller is the Kerberos
server. The Kerberos key distribution center (KDC) and the
origin of group policies are applied to the domain.
