Every time any domain account logs into a Win2k8 server, it generates an error such as :

Security: 675: NT AUTHORITY\SYSTEM: Pre-authentication failed: User Name: vbroker User ID: %{S-1-5-21-448539723-1606980848-682003330-3195} Service Name: krbtgt/<domain> Pre-Authentication Type: 0x0 Failure Code: 0x19 Client Address:

Domain is 2003 Native.

What other information is needed to troubleshoot?  Failure code 0x19 means that the kerberos pre-authentication failed.

DCdiag, netdiag, and repldiag show no interesting information about the matter.
