belt not turning with engine on

[rtognazz]

I have a issue where my drive belt does not turn with the air conditioning on even though the engine is running and the crank shaft is spinning. I replaced the belt and it didn't help. I also hear a bunch of rattling down by the crank shaft. When I remove the belt, all pulleys spin freely and so does the air compressor. Any thoughts?
