Denied Queries and Updates

Hi...

I recently had to migrate to a new box and to Solaris 9 from solaris
8. I am having lot of denied requests and denied updates for what my
DNS server is not resposnible for. For example lets say my DNS server
is on subnet 10 and doesnt have any inofmration for subnet 41 and 144.
I am getting queries from a box on 144 and updates from 41. nslookup
for these IP addresses from other boxes also fails. What should be
done here?

Thanks..
