Good morning. I have been successfully using PXE with several images via SCCM, but last week we stated to see an issue. when booting to PXE we get the following screen and we are unable to proceed. after a minute the device reboots. any assistance would be appreciated. if we connect a USB dongle that is registered in SCCM we are able to proceed, but that is not ideal as we have only a few dongles and many devices to image
