[Intel 82578DM Nic for MDT2010 64 bits]

OK fixed now.

Go to Intel and get v15.7 version of PROWinx64.exe

http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18713〈=eng

Extract them out of the .exe file.

Import drivers into Deployment Workbench, update Workbench and select the option that rebuilds the boot images ...LiteTouchPE_x64.iso, ....extract the files from the ISO and copied on my USB boot drive - all good, able to boot and deploy.

Cheers.

I have the exact same issue, the x64 drivers are not used during Winpe boot to connect to my OS distribution point during an OS deployment using Deployment Workbench.

Ive checked the Lenovo web site and am using the latest driver.

Might check the Intel web site to see if there is a newer driver.
