[Dnsmasq-discuss] DHCPDECLINE from windows vista clients

[Salatiel Filho]

I have dnsmasq serving dhcps for a small network, about 250 clients...
Clients are migrating from windows xp to windows vista or windows 7
and i started to get lots of problems where they just do not get the
IP from dnsmasq....

The log shows DHCPDECLINE...

it appears to be related to  DHCP BROADCAST flag.

There is a workaround by editing a registry key but it is too
complicated set registry keys on clients...
We are not a domain  , so can not apply gpo policies...

Is there a ways to make dnsmasq answer "correctly" to windows vista clients ?
