We are still using SMS 2003. The advanced client submits its H\W inventory as a "delta" inventory from the previously submitted inventory. We have a script, shown below, to force a full inventory. Is there a way (e.g. MOF edit) to force full inventories everytime?

Dim strComputer,strNameSpace,strClass
Dim ObjWMIService
strComputer = "."
strNameSpace = "root\ccm\invagt"
strClass = "C00000000_0000_0000_0000_000000000001"

Set ObjWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _
strComputer & "\" & strNameSpace)

'on Error Resume Next
objWMIService.delete"C00000000_0000_0000_0000_000000000001"
'On Error Goto 0

Eeew! Why? Instead of just dealing with normal delta inventory, it'd have to churn through, what...10MB worth of mostly redundant inventory data for every machine every time?

What problem are you attempting to resolve with a full HW inventory?

We have a "Backup and Restore" utility that captures a Ghost image of the machine and stores it on the network. When the backup is restored, it does not send an inventory because from its perspective nothing has changed since its last inventory.

We traditionally use this feature when we are doing software deployment testing. If you install anything onto the computer in the interim between its last inventory and the Ghost image, it is "orphaned" in the central database. For example, assume my machine inventories at 9:00 AM and I commence the backup at 9:30 AM. Later, I deploy my test application at 10:00 AM. Once the inventory for that new software goes forward, it is in the central database. Then "restore" the machine.

At this point, it is sitting there thinking it has the exact same configuration as it did at the 9:00 AM inventory. So, when the next inventory rolls around, it computes no change. As a result, it does not update the inventory. As a result, the test application is still in the server inventory.

Thus, the computer is set back in time to a point where it is happy with itself, despite the intervening test installation.

This will fix itself after 2-3 inventory cycles. The next time the inventory is sent up the SMS site server will see that the data is out of sequence and request a full inventory from the client again.

Not sure how to enable it to always do Full (thinking that may produce undesirable effcts if you did anyway) however you could always trigger a full inventory via a script I would imagine. Maybe have it as a startup script? Just trying throw stuff out there. ;)
