ignore FQDN 2003 DHCP server

Is there any way to ignore the client's response of their FQDN (DHCP
option 81)?
I know there is a way to do this in ISC's DHCP server (used in Linux as
dhcpd) with the option of "ignore client-updates;" in dhcpd.conf.

There really should be a way to do this in windows, since without AD
and without going around to each machine or doing a login script the
client's all report their FQDN as only hostname. and not
hostname.mydomain.org. I would think it would be quite easy to have
this feature in 2003 DHCP if it currently is not, which I'm hoping
someone here will be able to tell me that there is an option hidden
away somewhere.

Good Day,


Take a look at this Artical, i think this is what you want.

I've read through that article before, and did again. I have DDNS
setup just fine, as long as the client has "Use This connection's DNS
suffix in DNS registration" checked then it register's with DNS just
fine (in this case the client is sending the correct FQDN of
computername.domain.com in DHCP option 81).

DDNS also works correctly if I have both "Register this connection's
address in DNS" & "Use this connection's DNS suffix in DNS
registration" (in this case the client does not send it's FQDN in DHCP
option 81 because it is set not to register).

The default for Windows XP is "Register this connection's address in
DNS" checked and "Use this connection's DNS suffix in DNS registration"
unchecked. Which means that by default a Windows XP client will try to
register the FQDN of computername. instead of computername.domain.com.
Meaning that if there is a way for a 2003 DHCP server to ignore option
81(FQDN of client) and just register the client with DNS using option
12(client's hostname) and then appending the domain name.
