GN4 logs some events in the EventViewer of Windows. They are stored in a dedicated event source called TeraGN4. The logged events are:

-user login/logout (Login)

-server startup/shutdown (ObjUIComputeErr, ImportExportErr)

Specify the EventViewer key set to false to disable the EventViewer logging. If the key is missing the default is true.

For example:

<add key="Db.EventViewer" value="false" />
