One further question - if I am running my own DNS server (on Windows SBS2011) where does the DNS database come from? In setting things up I don't seem to have been asked for any reference DNS site? DOes it generate its own list - if so where does it get the translations from (excuse my ignorance if I am being totally dim).-Carol Haynes
(40Hz beat me to it, but I'll add this anyway) By default an Windows DNS server will forward external DNS requests to the internet root (DNS) servers. So if you want to use an internal DNS server - like for a domain environment - you would configure all client machines to use the
internal DNS server
only. Then in the forwarders tab if the DNS server configuration dialog you would add the OpenDNS servers ... Which will cause the server to stop sending requests to the root servers, and forward all resolution requests to the specified servers.
I've been using the OpenDNS servers for all of the networks managed by our company for a year or so and have absolutely zero complaints.
