cjjdool - thanks for that, appreciated :respect-054:
I didn't even consider the workgroup name changing, and I certainly wouldn't have known where to set it.
I've updated the 'smb.conf' file, but I still don't see the PC in the list on the AZ Box media player, even after rebooting the box and PC. I'll keep digging and see if I can find anything.
Thanks again.
