Thank you for your replying ! I understood that I should not enable 
that option with Windows 2003 server, but why should not dnsmasq's 
dhcp listen from Windows 2003 server ?
Is there any difference between Linux server and Windows server ?

In such a case, how can I specify the dnsmasq's option ?
For example, should I specify "--interface" option with the interface
which is not served DHCP addresses from a Windows 2003 server ?

    thank you

Saori.
