Domain Trust Relationship Implementation

Applies To: Windows Server 2008

The Windows Time service establishes a trust relationship with the domain. When a time server returns an authenticated Network Time Protocol (NTP) packet to a client that requests the time, the packet is signed by means of a Kerberos session key that is defined by an interdomain trust account. The interdomain trust account is created when a new Active Directory domain joins a forest, and the NetLogon service manages the session key. In this way, the domain controller that is configured as reliable in the forest root domain becomes the authenticated time source for all the domain controllers in both the parent and child domains - and indirectly for all computers in the domain tree.
