I am trying to use DNS to block websites by basically using 127.0.0.1 for any domains that I want to block. I originally thought that I could edit the hosts file on the DNS server (Win2k Server) to block the sites but that only works for the local machine and does not affect the PCs asking the DNS server for lookups. So, is there a way to make the DNS server look at the hosts file first before asking the DNS server it is set to forward its queries to? I am currently using 2k sever but I am not opposed to using RedHat or some other form of Linux or Unix.
