Kerberos Key Distribution Center (KDC) is a network service that supplies session tickets and temporary session keys to users and computers within an Active Directory domain. The KDC runs on every Domain Controller as part of Active Directory Domain Services (AD LDS).

The Security Account Manager (SAM) database on the Windows Client is used to authenticate requests from the Key Distribution Center. The SAM database MUST be available for the Kerberos client authentication request to succeed.
