Post pagination broken after query_post modification

Here is the scenario:

1) I have a homepage.php that I use as a static page for my Front page.
2) I have a blog page that use the Default Template(index.php) as my static page for my Posts page.

I used two categories in my homepage.php that I want to exclude from blog page. So, I did this:

$catIDs = get_cat_ID( $cat_name='Featured' );
	$catIDs .= ',-' . get_cat_ID( $cat_name='Services' );

	$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
	query_posts("cat=-$catIDs&paged=$paged");
		if (have_posts()) : while (have_posts()) : the_post(); ?>
			<div <?php post_class(); ?>>
...

The content from those two categories don’t show up on my blog page, but you can still navigate from post pagination.

Any tip here?
