You usually need ‘power users’ group membership to manage shares via the MMC.
As I understand it there are hidden or embedded capabilities in the power users group that give you similar functionality to ‘Power users’ on a native windows platform.
Depending on the client software the users are running the MMC on they may also need read only access to the C$ share on the Filer (due to how some Windows clients work).
This is only a share level permission requirement and will not require NTFS rights on vol0 (assuming your vol0 has an NTFS security style).
I would point you to some knowledge base articles but I only have email access as I type this response.
