Logging options
The default value for Schannel event logging is 0×0000 in Windows NT Server 4.0, which means that no Schannel events are logged. In Windows 2000 Server and Windows XP Professional, this value is set to 0×0001, which means that error messages are logged. Additionally, you can log multiple events by specifying the hexadecimal value that equates to the logging options that you want. For example, to log error messages (0×0001) and warnings (0×0002), set the value to0×0003.
| Value | Description |
| 0×0000 | Do not log |
| 0×0001 | Log error messages |
| 0×0002 | Log warnings |
| 0×0004 | Log informational and success events |
