You set the Hardware Inventory Client Agent settings, in Microsoft System Center Configuration Manager 2007, by modifying the necessary site control file settings.

To modify the Hardware Inventory Client Agent settings

Set up a connection to the SMS Provider.
Make a connection to the Hardware Inventory Client Agent section of the site control file by using the SMS_SCI_ClientComp class.
Loop through the array of available properties, making changes as needed.
Commit the changes to the site control file.

Example

The following example sets the Hardware Inventory Client Agent settings by using the SMS_SCI_ClientComp class to connect to the site control file and change properties.
