When you restart after running Dcpromo.exe on a Windows Server 2003 computer, the System event log contains:
Event Type: Warning
Event Source: LSASRV
Event Category: SPNEGO (Negotiator)
Event ID: 40960
Description: The Security System detected an authentication error for the server ldap/dca.acc.local.
The failure code from authentication protocol Kerberos was "There are currently no logon servers available to service the logon request.
(0xc000005e)".
Event Type: Warning
Event Source: LSASRV
Event Category: SPNEGO (Negotiator)
Event ID: 40961
Description: The Security System could not establish a secured connection with the server ldap/dca.acc.local.
No authentication protocol was available.
This behavior occurs because the Windows Time service (W32Time) started before Directory Services. You can safely ignore the above warnings in this scenario.
