Hi buddy, first of all great blogging!
Secondly we are having a nightmare pxe booting the sp3.
We have ip helpers in place. Running server 2008 r2 sp2, sccm 2012 r2. All other tablet, UEFI, PXE perfectly.
We see the pxe screen but it just drops through and we end up having to build via usb boot.
The sccm pxe log just says 'not serviced' next the sp3 Mac and guid, we have tried docking stations, usb nics, all MS approved for surface pro 3.
Any ideas? I have already built 34 but we need to hand the builds to the help desk as we have created a zero touch build in place for them where Mac and asset is all that is required and I'm afraid explaining usb boot to some of these lads will be a nightmare! (I'm not kidding!)
