Each site that a client belongs to that has hardware inventory enabled will receive the client's hardware inventory.
To determine which hardware properties to inventory on clients, SMS uses only the SMS_def.mof file from the principal site. If the principal site does not have a custom SMS_def.mof file in its SMS\Inboxes\Clifiles.src\Hinv directory, Hardware Inventory Agent uses the default SMS_def.mof file.
When any site requests a resynchronization, Hardware Inventory Agent generates a complete hardware inventory file (Hinvdat.hic) and sends it to all of the client sites. (SMS requests a resynchronization whenever a hardware inventory file requests an update to an inventory group that does not exist in the SMS site database or when a client attaches to a new site.)
