Hardware Inventory not updating – SCCM 2012

I had a client where the hardware inventory had not updated in 3 months.

On the client in C:\Windows\CCM\logs\InventoryAgent.log I could see that the client sent the inventory to the management point “Inventory: Successfully sent report. Destination:mp:MP_HinvEndpoint”

I checked MP_Hinv.log on the management point (located in C:\Program Files\SMS_CCM\Logs\MP_Hinv.log) and could see that it received the file from the client

Then I checked dataldr.log on the site server to see if it was processed. Searching for the client name in this log, you can see at the bottom there was a Delta Mismatch.

Now I had to do a full hardware inventory resync on the client. I used the steps from this post to do a full hardware inventory cycle on the client

I confirmed that the client was listed in the log MP_Hinv.log but could still not see it in Dataldr.log

I then opened up the SCCM 2012 console and checked \Monitoring\Overview\System Status\Component Status\SMS_INVENTORY_DATA_LOADER
Then it pointed me in the right direction. I saw “Inventory Data Loader failed to process the file C:\Program Files\Microsoft Configuration Manager\inboxes\auth\\Process\HJWO0QKN.MIF because it is larger than the defined maximum allowable size of 5000000.
Solution: Increase the maximum allowable size, which is defined in the registry key HKLM\Software\Microsoft\SMS\Components\SMS_INVENTORY_DATA_LOADER\Max MIF Size (the default is 5 MB), and wait for Inventory Data Loader to retry the operation.”

I checked C:\Program Files\Microsoft Configuration Manager\inboxes\auth\\Process\ file size and saw it was over 5mb but under 7mb. I increased the registry to 7mb from the key above.

In about 10 minutes I tried the Hardware Inventory Cycle again and this time it was successfully processed in the dataldr.log.

The hardware inventory had successfully updated.


Forcing client to do a full hardware inventory sync – SCCM 2012

On the client run Wbemtest.exe as admin and click Connect

Connect to “root\ccm\invagt”

Click Enum Classes

Click Recursive then OK

Double click on InventoryActionStatus

Click on Instances

Delete the inventory action status instance for hardware inventory ({00000000-0000-0000-0000-000000000001}).

Initiate a hardware inventory cycle. This will now do a full scan.
