Question : Block DNS Lookups for certain domains

using windows 2003

i have been asked to block name resolution for certain domain names on the internet.

currently we use AD DNS for internal with Forwarders to resolve external names.

Is there a way i can put a block on certain domain names so our users cannot look them up?

thanks

Answer : Block DNS Lookups for certain domains

i have been asked to block name resolution for certain domain names on the internet.

So why dont you disable ICMP on the firewall? from inside to outside?

ping and tracert also dont work when adding those domains to dns and point them to somewere else.
