hmmmm...
our experience with NCD winterms is different from yours... we have not
seen a problem where they send us an invalid option or "magic cookie" in
their requests, and in our case they don't send BOOTPREQUESTs anyway -- they
use DHCP....
have you captured a packet trace from one of the offending terminals? there
are only a few, very specific reasons why parse_options() and
parse_option_buffer() will set the options_valid flag to false: missing or
invalid magic cookie and the inability to obtain a buffer for storing an
option being the most likely to occur....
if your winterms are not sending a proper magic cookie, they are broken!!
contact your NCD rep for an update!
I am also puzzled why they are not sending DHCP requests....
now I have seen other vendor's winterm implementations do some really weird
things, such as expecting the server to act as non-volatile storage for
certain bits of client data, expecting the server to return data in options
129-254 (but without requesting those options!), and a few other bits of bad
behavior, but the NCD implementations seem to be pretty solid....
