SQL 2014 cluster shared volume

Hi,

I have testing SQL 2014 cluster in my lab to see how it's performing. 2xserver 2012r2 (virtual machines). There are some weird issues that are putting me in dust.

1. If I try to backup/restore database, I cannot select data path from gui. (I cannot "browse")

2. I cannot connect applications to databases (sqlclustername\instance)  - permissions denied on cluster shared volume.

Can you please give me a hand on this?

Thank you.
