You won't see this if your workstation accesses the share over CIFS. Previous versions can be seen on a Windows server in a SAN environment, when SnapDirve comes into play & does VSS integration.
In a file sharing environment you can always navigate from any client to ~snapshot subdirectory of the share in question & you will see all the snapshots taken of that volume.
The thing you can change on the filer side is whether that subdirectory will be explicitly visible, or hidden (yet still accessible if a person knows what to type in address field ). You do that by ticking / unticking the box in FilerView.
