As hpa already pointed out in his reply to

  http://syslinux.zytor.com/archives/2005-October/006033.html

    It worked before because previous versions of ISC DHCP defaulted to
    "next-server == boot server".  They removed that default without warning.

So while "pxelinux[.0]" is loaded from "boot-server", "pxelinux" itself
is left without a valid ip-address (next-server) to continue from.

I don't know, if it would be possible for "pxelinux" to derive "next-server"
from "boot-server", in case that "next-server" is empty.
But perhaps the "boot-server" information is no longer available when
"pxelinux" is executed, otherwise -- I guess -- hpa would have already
implemented this.

P. S.: Did you actually reply to a previous post?
  I can't find any "In-Reply-To" header and neither does thunderbird.
  So your message isn't grouped into the thread ...
