I know it is possible to add computers to the managed devices list via barcode web form, but then after they are imaged and the agent is installed can the system recognize the existing record and update it? I tried this, but the agent created a new record, rather than updating the existing one. I had hoped that if it found a record with the same device name, serial number, MAC address, etc., it would just update it.
Did I miss a step, or is this not possible?
