Enforce Asset Discovery without overwrite
I have a set of assembled computers (non OEM) over AD. I configured agent, network and AD scans, however, each time, some computers are overwritten because most of computers I have are assembled with no service tag or ID. How can I overcome this and successfully input all possible computers without overwriting existing ones?
Another inquiry goes for network printers, how can I move a scanned asset from Workstation to printers category?
