I will try the Unknown Collect and let you know how it works out.

I am looking at this link from MS on how to setup Unknown Computer Support and under the Boot Media it says you need to enable Unknown support, but I am not seeing that option anywhere https://technet.microsoft.com/en-us/library/gg712337Can you assist me with this? I have enabled Unknown Support in the DP PXE, but I am not sure how to add a new Boot media to SCCM for Unknown support.

Mike I have an older SCCM 2007 that is in the boundary group, but the PXE is not point to that server.

My IP HELPER is point to my new SCCM 2012 R2 server for PXE.

I can remove the PXE role from the older SCCM 2007 since it is not even used anymore for OSD.Do you think my older SCCM 2007 machine could be throwing this for a loop. It just points to WDS which in turn points to boot files. A certain Mr Nystrom gives full detail here: https://deploymentbunny.com/2016/02/29/osd-how-make-pxe-work-in-configmgr-osd-mdt-and-wds-work-perfectly-fine-stop-using-dhcp-option-66-67/ Removing the DP is a last resort only, once you have eliminated all other sources of conflict.On my new SCCM 2012 there is only on DP and only the Primary site.. Note you always need both architectures, x86 and x64 boot files regardless of what OS you are building. As I said, the DP is set correctly so I'm suspecting something else is pointing machines to the wrong place.With R2 they simplified things and made it a setting per Distribution Point.This makes it easy to enable and flexible because you can restrict it very easily to specific DPs.
