WinPE Bad Magic, right names

[Luvan]

i have followed this guide:
http://ipxe.org/download

But i get connection time out...
This is the embedded script:
#!ipxe

dhcp
chain http://upkeepernas01/upkeeper/boot.ipxe

And this is what i get:


i tried to change the path to this in boot.ipxe:
#!ipxe

kernel http://upkeepernas01/upkeeper/wimboot
initrd http://upkeepernas01/upkeeper/bootmgr bootmgr
initrd http://upkeepernas01/upkeeper/boot/bcd BCD
initrd http://upkeepernas01/upkeeper/boot/boot.sdi boot.sdi
initrd http://upkeepernas01/upkeeper/boot.wim boot.wim
boot

But same result:


The files are there, if i replace my compiled undionly.kpxe with the orginal, hit CTRL+B and run boot.ipxe manually, it works fine...

What im i doing wrong?
