In the past, I have implemented for myself a local DNS server running Ubuntu and BIND which would block advertisements. Basically the local DNS server had a big zone file which blocked all of the major advertisement domains
I have a client who wants a similar thing configured on their business network, but they have two servers - one is running SBS 2003 and the other is running Server 2008. They do not want Linux.
Is there any similar method for configuring a Windows DNS server to perform ad blocking?
