What languages are those 1909 machines? If one is en-ud and the other is en-GB you have to include all files in that language.
I’m having issues with numerous… I had one that had russian fail (that one made sense as I didn’t have that file included) and I’m having ones with just english fail, which I have those files…
What I meant in the last reply was that I literally copied all files/languages for Microsoft-Windows-ActiveDirectory-DS-LDS-Tools-FoD-Package and it still fails… I just don’t know which file it’s looking for!
