I figured such. The usb method on my offline imaging switch is redundant since pxe works fine on that. Just would have been nice to be able to image remotely booting via USB, kind of like Acronis+mapping to an SMB share that stores the images. If only my network team would enable tftp/pxe on their dhcp servers. We have it only on our hq subnet but it is being used by SCCM, and SCCM takes a very, very long time to image a PC. We only use it to get a base Windows 10 image and work on it from there, then capture/upload our custom dept images to the FOG server.
