When viewing the computers hardware inventory the "Serial Number" is blank, contains "N/A" or the words "Serial Number".

During the assembly of the computer the hardware manufacture has not entered the "Serial Number" into the BIOS/Firmware.
These two commands, when run on the target computer, can be used to verify the "Serial Number":
1: "Get-WmiObject win32_bios | select Serialnumber”
2: "wmic bios get serialnumber"
Contact the hardware manufacture and request the process for manually entering the "Serial Number" into the computers BIOS/Firmware.
Once this is done, either wait for the next scheduled run of the hardware inventory scan or force a scan to run now by taking the option "Asset Job/Activate Job check" from within the DSM Explorer GUI all computers view.
