A couple things going on:
1 - it appears the involved computer has some sort of hardware issue (i.e. bad ram, etc.)
2 - did a query for the MAC and found that it existed in the client list with a far different name than it should have been.
3 - rebooted the network switch, also seems to have helped.
I'm still getting this message on the PXE BIOS boot screen:
Pending Request ID: 3
Message from administrator: Configuration Manager is looking for policy.
But it continues to boot and I can image the machine. I tried several machines and they are all receiving that
