@jdd49 While I don’t believe its a linux issue because if you turn off the computer and back on any “bad stuff” that linux might do to these machines should be gone. The FOS engine (kernel) doesn’t (AFAIK) update any firmware so there is nothing to leave behind.
If you re-image one of these machines with the windows DVD does it work correctly? I would still like the 5 questions I asked answered too. They will help the developers understand your current landscape too.
@Developers Do you have any ideas here?
