Packet filters don't pass the traffic through the application filters.
Thus, your DMZ-based DNS servers can't take advantage of the DNS intrusion
filter ISA includes..

Hi Steve
I understand that they should be in the DMZ...but for the next few months and a
tight budget this cannot be done.
I know this question is stupid but I will ask anyway.....What risk is there in
having the DNS NOT in the DMZ....am I at risk via port 53??
William

you'll need incoming / outgoing dns query packet filters, on each ISA Server as
well as publishing them.
