NAS with Finder is not working right in OS X Mountain Lion 10.8.4

Since my last update from OS X Mountain Lion 10.8.3 to 10.8.4. The finder sees all of my NAS but i can't access them anymore by SAMBA or AFP. Why is this? I should not change settings in my NAS's if this is only an UPDATE. All of my NAS Firmware is updated and still nothing works.

I factory reset my Mac Book Pro just like i purchase with the install CD in the box and did all updates from Apple and it works like a charm.

Mountain Lion was purchase for a better OS X and i can't use it. I'm back to OS X Snow Lepard 10.8.6 and everything run very nice and all of my NAS can access within a click.

What did go wrong in the OS X Mountain Lion 10.8.4 for this to happen?...... 😠
