I don't know about ms dhcp, but there should be an option like isc-dhcp has (default dhcp-parameter-request-list): ... match if substring (option vendor-class-identifier, 0, 7) = "PXEClient"; # removing windows specific options to save space for FreeBSD; default dhcp-parameter-request-list 1, 3, 6, 12, 15, 17, 23, 28, 29, 31, 33, 40, 41, 42, 144, 150, 208, 209, 210, 211, 230, 60, 43; notice that 17 is in there danny ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"

I did the dump catching ip broadcasts (attached file), hope that is the correct one: windump -nvvv -s 0 -w pxedump.cab ip broadcast I would like to try to get rid of "^@" characters but i am going to need instruction what exactly do in need to do in order to accomplish it.
