@cml Thanks for the link to the debug undionly.kpxe it helped us solve our problem right away. Turns out we had a rogue DHCP server that was issuing a second lease after just before the hand-off to the default.ipxe file. That lease didn’t have an ip for the tftp server. As soon as we shut it down we got a successful boot!
