Ethernet Connectivity lost during imaging
NOTE: A good working knowledge of Windows Imaging deployment using Microsoft SCCM 2012 or MDT 2013 is recommended to this article.
If you are PXE booting your Dell laptop using a USB Type-C to Ethernet adapter (dongle, DA200, WD15 dock, etc.), you may encounter a loss of network connectivity when the computer reboots during the imaging process.
If the adapter is disconnected from the USB Type-C port and reconnected, then you select the try again option, connectivity is restored.
Cause
This issue is caused due to the RealTek Ethernet driver. Updating the RealTek Ethernet driver to the latest version helps resolve the issue.
