This guide provides you with the fundamental concepts used when troubleshooting Kerberos authentication issues. A Kerberos-related error is a symptom of another service failing. The Kerberos protocol relies on many services that must be available and functioning properly for any authentication to take place. To determine whether a problem is occurring with Kerberos authentication, check the System event log for errors from any services such as Kerberos, kdc, LsaSrv, or Netlogon on the client, target server, or domain controller that provide authentication. If any such errors exist, there might be errors associated with the Kerberos protocol as well. Failure audits on the target server's Security event log might show that the Kerberos protocol was being used when a logon failure occurred.

This topic for the IT professional describes new capabilities and improvements to Windows implementation of the Kerberos authentication protocol in Windows Server and Windows 8.

Initial user authentication is integrated with the Winlogon service single sign-on architecture. AD DS is required for default Kerberos implementations within the domain or forest. In Windows Server and Windows 8, Kerberos authentication can be leveraged to address lack of connectivity to the domain controller from outside the corporate firewall.
