Audit Intranet User's File Uploads

I'm a jr. admin, we have a number of network shares at my work. It's a constant struggle to keep users from abusing our storage space and uploading mass amounts of data. Is there some sort of auditing system in Windows Server 2008 x64 edition where I can see whos uploading what, how large the files are, what date this occured, etc? For example if INTRANET\bobdole uploads 5 GB worth of data to our N: drive, I want to know about this or be able to track this.
