322756 How to back up and restore the registry in Windows XP and Windows Vista


SUMMARY

Microsoft Windows 2000 and Microsoft Windows Server 2003 offer the capability of tracing detailed Kerberos events through the event log mechanism. You can use this information when you troubleshoot Kerberos. This article describes how to enable Kerberos event logging.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Enabling Kerberos Event Logging on a Specific Computer

  1. Start Registry Editor.
  2. Add the following registry value:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\Kerberos\Parameters


    Registry Value: LogLevel
    Value Type: REG_DWORD
    Value Data: 0x1

    If the Parameters subkey does not exist, create it.

    Note Remove this registry value when it is no longer needed so that performance is not degraded on the computer. Also, you can remove this registry value to disable Kerberos event logging on a specific computer.
  3. Quit Registry Editor. The setting will become effective immediately on Windows Vista, on Windows Server 2003, and on Windows XP. For Windows 2000, you must restart the computer.

You can find any Kerberos-related events in the system log.

MORE INFORMATION

Turning on Kerberos event logging is intended only for troubleshooting purpose when you expect additional information for the Kerberos client-side at a defined action timeframe.

From a general point of view, you may receive additional errors that can correctly be handled by the receiving client system without the user interference. Therefore, it does not reflect a severe problem that must be solved or even can be solved.

For example, an event log 3 about a Kerberos error that has the error code 0x7 KDC_ERR_S_PRINCIPAL_UNKNOWN for Server Name cifs/<IP address> will be logged when a share access is made against a server IP address and no server name. If this error is logged, the Windows client automatically tries to fail back to NTLM authentication for the user account. If this operation works, receive no error.
