When troubleshooting Kerberos Integrated Authentication issues, it might be required to enable additional logging to identify the root cause. On Windows machines enable Kerberos Event logging for additional information logged into Windows Event Viewer > System log.
 
 
 
Follow the steps below to enable Kerberos Event Logging:
WARNING: Before following the steps below, ensure to backup the registry of the Windows machine.

1. Start Registry Editor.
    
2. Add the following registry value:
   
   Path: 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 manually.
    
   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 Server 2008, on Windows Vista, on Windows Server 2003, and on Windows XP. For Windows 2000, you must restart the computer.
