Yes all the nodes are on the same version as the main server. They had the files/folder in the path /var/www/html/fog/service/ipxe, but the clients booting from one of the storage nodes would not display the menu until we copied over the folder from the main server. We did make some modifications to the main server’s FOG_TFTP_PXE_KERNEL so that is why I had to copy it over to the clients.
