@Wayne-Workman Thanks very much for your help.
It turns out that you need to fill out this part CORRECTLY and with the ACTUAL path and not the MISTYPED wrong one as I had!! Whoops!! Check check and check again,
This is the part that my ineptitude caused all the issues:
First in your /etc/exports add this line:
/var/www/fog/iso/15.04_64 * ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)
