In the meantime I have adjusted the language in English, removed the DVD drive still attached, started this one Nas repeatedly newly and tried again to create a user. It was the same result. I have copied a couple of files on a Share and, once more, while the files are still copied, I have tried to create a user again. And see there, the user, I had this one tried approx an hour before it became to lay out listed. Now the Function is ok, But I do not know the solution. ????
