I recently discovered that on Mac OS 10.7 (aka Lion) my documents on my NAS are arranged in the order "Z, Y, X, W, V, etc...". So how do I specifically change this setting of the arranging order? The bars on top (in 10.6) are now gone...
You need to change the view properties of the Finder window. Here's how to do it using Menu commands.
You should now see the Finder window property headers and then you can click on Name to sort ascending or descending.
