I am not convinced that anything changed that would matter for your 
description. 
I just mounted as you describe over cifs with no problem after I realized
that Linux loopback mounts open CD images read/write (not read-only).  
You must
have write permission on the server .iso file to do mount lookback with 
default flags as you
describe (does not matter whether your server is windows or Linux)

    mount -o loop /server/dir/file.iso /mnt

If you mount the iso readonly:
    mount -r -o loop /server/dir/file.iso /mnt 

it will work (or change the access control on the server file).  You
also may want to turn off permission checking on the client side
(via cifs client mount option "noperm") if your uids on client and server 
do not match.
