Windows has no support for Rock Ridge or its Amiga extensions, which is why you'll be missing attributes, comments, and most likely case-correctness, if the disc does not also use Joliet. (CIFS/SMB lacks extensions for the extra attributes as well.)
Amiga OS needs ATA over Ethernet (or iSCSI, but AoE is a lot easier to implement, since you don't need an IP stack).
