I am having an issue with our Lenovo Thinkpad Yoga's connecting to our MDT 2012 server. When I boot to Windows PE and try to connect to the deployment share I receive the message, "no networking devices found on this machine!." I was able to find a link to MDT drivers on the Lenovo site https://support.lenovo.com/us/en/documents/ht074984. I have imported this driver into MDT and created a selection profile. I have ensured that the driver is in the boot image. I have also tried injecting the drivers manually while booted into PE. Just for good measure I even tried the drivers for the Think Pro One Link Dock and for the USB to ethernet dongle. I have researched the web for solutions on this issue and tried all that I have found thus far. Oh by the way I have even totally recreated the MDT server from scratch and I still have this issue with the Yoga. I have other models of Lenovo computers and I can connect to the MDT server in PE on these machines. Any advice or assistance would be highly appreciated as I am under the gun to get this up and working.
