About 11-12 years ago, we ghosted Compaq Prosignia 330? desktops with
Intel NICs.  When we ghosted them, some of the desktops ended up with
the same MAC addresses on the NICs.  It turned out that there were two
different models of Intel NICs in the desktops and ghosting the
desktop with the second type of NIC resulted in the MAC address from
the original Ghost computer put on that computer.  Updating the NIC
driver resolved the issue.
