What posts exactly are not shown?
In your code there are no page links (pagination).
Could it be that you just see the the number of posts according to the respective admin setting?
In addition, I just have been learned NOT to use query_posts. Why would you use it there anyway? Assuming, this is a post-showing template (e.g., index, front-page), you just have to write:
<?php while (have_posts()) : the_post(); ?>
DO YOUR POST STUFF
<?php endwhile; ?>
