So this is what I have typed in the share box but it wont accept it
No just Downloads, I've just done this on a VM;
So Remote Mount -> Add, enter a name for it to appear in OMV, Server -> IP Address, Share -> Name of the share on the windows box, username and password, I entered the my login details for my windows machine, save, apply, this worked for me, but it errored when I tired to mount it, so reboot omv and it's mounted.
