The AspErrorsToNTLog property specifies which ASP errors are written to the Windows event log. ASP errors are written to the client browser and to the IIS log files by default.
AspErrorsToNTLog is set to FALSE by default, and modifies the AspLogErrorRequests property in the following ways:
If AspLogErrorRequests is set to TRUE, and if IIS fails to write an item to the IIS log file, the item is written to the Windows event log as a warning, regardless of the value of AspErrorsToNTLog.
100, 101, 102, 103, 104, 105, 106, 107, 115, 190, 191, 192, 193, 194, 240, 241, and 242
This property does not control logging requests to the IIS log files. For more information about logging requests, see the LogType and DontLog properties. Also, this property does not control IIS Event Messages, which are always sent to the Windows event log.
This property is a process-level property.
If this property set at the Web service level, it is applicable to all in-process application keys. Metabase property settings at the Web site level or lower are ignored for in-process applications unless the Web site key is isolated as an out-of-process application.
You can configure this property at the following locations in the IIS metabase.
