i now have 2 machines in the office with this issue: user logged in as administrator, when trying to access any type of storage device getting "Drive not Accesible, Access isDenied" message. This happens on all flash drives, CD drive, DVD burner, etc.. We can only seem to access the C:\ drive. Seems to come on suddenly, not sure if caused by an automatic update overnight as nothing else changed on these machines. Both machines are Acer running Windows XP Pro Anyone have a clue? Thanks,Maureen
