Heh.  This happened to me; I nuked someone's personal machine.

OTOH, we re-image machines as a matter of course, so we use groups to
place machines into the "never re-image because they aren't ours"
category now.

My environment is pretty different from most, though.

In anyrate, in answer to the first posters question:

You need to get them to set DHCP option 140 to the hostname of your
imageserver.  They should also set "next-server" (a standard DHCP
option), to your TFTP server, and "filename" to your pxelinux boot file
(in my case, /pxelinux.0).  That's enough to make it all work.  They
then just need to make sure that your hosts get those options sent to
them.

I'm not sure why "filename" and "next-server" aren't options in the ISC
dhcpd configuration; they may actually not be DHCP options as such.
