INFORM not working properly?

It looks like a "group" statement is also not matched on INFORM.

I tried the following:
group {
	option domain-name-server;
	host {

The group option for domain-name-server IS picked up during an initial 
REQUEST/ACK, but not with an INFORM/ACK. (This is just an FYI.)

Is there any more info on windows and DHCP INFORM? I did some packet 
traces and it looks like the windows client will send several packets 
(half a dozen or so) all at once... then nothing for a period of time. I 
can't figure out why it's so "chatty".

Also, I don't see similar behavior with Mac OSX or Linux (RHEL) clients.
