Error messages that are related to the component that maps ABO interface calls to the configuration system in IIS 7.0 are logged in the %Windir%\System32\Abomapper.log file

This article discusses where to find error messages that are related to the component that maps Admin Base Object (ABO) interface calls to the new configuration system in Microsoft Internet Information Services (IIS) 7.0. IIS 7.0 logs these error messages in a log file that is named Abomapper.log. This file is located in the %Windir%\System32 folder.

IIS 7.0 does not use the metabase to store Web configuration settings like in earlier versions of IIS. IIS 7.0 uses a new integrated configuration system that is significantly different from the metabase. To maintain backward compatibility for the ABO interface, IIS 7.0 includes a new component. The new component is the Abomapper. This component is implemented by the Abocomp.dll module.

If an issue with the mapping metabase calls or with the ABO API calls causes an error to occur in the ABO interface, you can view the error messages to help you troubleshoot. Error messages that are related to the ABO interface are not logged in Event Viewer. Instead, they are logged in a log file in the following location: The following is an example of an ABO-related error message: For more information about IIS 7.0, visit the following Microsoft Web sites:For more information about configuration compatibility in IIS 7.0, visit the following Microsoft Web site:
