If you are seeing it in the K1000 computer inventory, I would check WMI first as this is how the KBOX gets inventory assuming you are using a Windows OS.

In a command prompt, run this: wmic get bios serialnumber

See what it returns. You might need to rebuild your WMI repository: http://blogs.technet.com/b/askperf/archive/2009/04/13/wmi-rebuilding-the-wmi-repository.aspx

I would try updating the BIOS first. If that didn't work, you could always reimage.

What BIOS Version is it running? Manufacturer? You can access the BIOS serial number by running this command
"wmic bios get serialnumber" (Without Quotes)

Or the machine was rebuild and what you are seeing is a new and old record. If the MAC address is the same, then its likely the same machine.

  • Actually, I just had another thought. If you replaced the motherboard on that machine, some vendors (most that I know of) will provide a tool to update the bios serial number. Either way, just to be sure, find the machine in question and visually check it.
