Deployment Solution (DS) 8.7.2 and older
Product limitation
Rows will disappear if image is deleted or if computer resource deleted.
A change to this behavior has been added to our ITMS 8.7.3 Release.
As a workaround these records can be removed with following SQL query:
---------
DELETE FROM Inv_PXE_Preboot_Images
WHERE _ResourceGuid NOT IN
(SELECT _ResourceGuid FROM Inv_AeX_AC_Client_Agent ica
WHERE ica.[Agent Name] = 'Deployment NBS Plug-in')
----------
