We have about 600 Venue Pro 5130 machines in our district, and we are running into a bit of trouble. We have all the drivers in the Boot x86 image (we also have a Boot x64, but these are 32-bit machines), and have the TS advertised to all unknown and known computers in the system, but only available via PXE. The issue is that whenever we UEFI boot for IPv4, it receives an IP address and then 'Succeed to Download NBP File' and then flashes and moves on to the next boot device. It never loads the WinPE environment or loads the boot image. Looking at the SMSPXE.log file, there isn't even a reference to the MAC address of the USB Dongle we are using, and we are 100% sure they are compatible with the Venue's PXE requirements (the Dell 0TFXX8 or SMSC LAN). Any thoughts?
