Have you looked at the smspxe.log, to see why they're getting rejected? I am assuming that you have a OSD task sequence advertised to the known computers (hopefully not "required," but still valid)?

I can PXE bare metal machines (unknown to SCCM) with no problems. However, if they are cliented PXE doesn't seem to work on these machines. I get the following: PXE Boot aborted. Booting to next device... PXE-MOF: Exiting PXE ROM. What am I missing here? Thanks, Brian
