I guess there's a RAS service installed on that machine?
If so, try either:

or apply the attached RAS patch for ISC DHCP - we use it, works grate!

first I'd like to say 'Thank you!' to all who replied to my question.

We got the problem also on an cable modem network :) so we don't have
control over what's on the network whatsoever.
I got this very handy reply from Leonard Hermens (thanks again!) witch
solves the problem:
It is RAS from NT.
We hate it, so I modified the code in dhcp.c to refuse them:
=======================================================
.
.
.
/* Modified: February 18, 1998 */
if (packet -> raw -> hlen > 6) {
/* note ("Denied RAS = %s from %s\n",
print_hw_addr (packet -> raw -> htype,
packet -> raw -> hlen,
packet -> raw -> chaddr),
packet -> raw -> giaddr.s_addr
? inet_ntoa (packet -> raw -> giaddr)
: packet -> interface -> name);
*/
return; /* don't process RAS don't DHCP anything */
}
/* END CHANGES */
switch (packet -> packet_type) {
case DHCPDISCOVER:
dhcpdiscover (packet);
break;
.
.
.
======================================================
Note that you can uncomment the 'note' code to log the denials. We just
ignore them and don't log because it fills our log files up.
The code presumes that the ethernet HW address is 6 bytes or less.
