    The man page for the shadow file ("man 5 shadow") gives us the details of the password field:
    Code:
               If the password field contains some string that is not a valid result of crypt(3), for instance ! or *, the user will not be able to use a unix password to log in (but the user may
               log in the system by other means).
    So the '!' indicates that the user cannot be logged in as using normal means. You could still act as the user by using sudo or su, or by using SSH with an accepted key.

    Also, Welcome to the forums. For future reference you can disable the smilies in your post by selecting the right option (disable smilies) before you submit your post.
    I tried to fix it for you but I don't think I can.

    EDIT: There we go, I figured it out.
