Heya has the wim file definately been updated and replaced on your WDS server?
What were the commands you used to inject the drivers into the wim file maybe it did not unmount and commit correctly?
Have had similar problem whereby if the folder was open with explorer and attempted to commit the wim would become corrupt.
Used the following which worked for me for the 800 series modies eliteonedesk and 820/840 laptops

Hope that helps
