Map Network Drive not working

Google showed up some results on how to map my drobo to other machines on my network (I would assume) but they don’t work.
I can ping by IP and friendly name and both reply back but the drive never lets me connect.
I have granted EVERYONE read/write access on the PUBLIC share

but the machine i’m trying to map from doesn’t see it in network or by typing \drobo5n\public OR \\public

any ideas on how to connect from more than the machine that has the drobo dashboard installed???
