Cant access library with my new Dell rack server

I got rid of my Qnap TS-212 NAS and replaced it with a 60TB Dell Rack Server, so I now have plenty of room to grow.

But, when trying to access the library on Kodi, I am having some administrator issues on the Dell Server. When I go to Files->add videos -> and Browse for new Share , I can see the server, but when I click on the server, I get the error: Operation Not Permitted. So its a setting issue on the server.

Anybody know specifically what settings I should be using? Is Kodi being blocked by the username and password of the server??

Much appreciated!
