About the Configuration.mof File
The Configuration.mof file is used to define the data classes to be inventoried by the hardware inventory client agent. Data classes can be created to inventory existing or custom WMI repository data classes or registry keys present on client systems.
The Configuration.mof also defines and registers the WMI providers used to access computer information during hardware inventory. Registering providers defines the type of provider to be used and the classes that the provider supports. WMI, and
Configuration Manager 2007 hardware inventory can only access registered providers.
About the SMS_def.mof File
The SMS_def.mof file defines the reporting classes used by the hardware inventory client agent to determine whether or not specific client data class information is reported. Reporting classes are based on the WMI repository data classes, and attributes
of those classes, existing on clients by default or added to them by customizing the Configuration.mof file.
Reporting class information in the SMS_def.mof file is converted into a reporting policy provided to clients during their normal computer policy polling interval. After the client compiles the new reporting policy, the reporting policy information
is stored in the client system WMI repository in the InventoryDataItem class of the Root\CCM\Policy\Machine WMI namespace.
