DNS restart on SBS 2011

I have to continue restarting DNS server, every day. We notice this when we can no longer access particular websites, but larger website (google, microsoft, etc) continue to run normally, after restart it works fine.

Any idea why this happens and how to fix?

Do you have a few examples of sites that quit working?

When I say sites are not working I am referring to general browsing of the internet, not internal sites. So in exploder we can go to google, microsoft, this website, other major sites, but smaller sites like www.whitemagazine.com.au, www.fedup.org.au, blog sites etc etc stop working....

What difference would it make what sites they are in particular?

Can you ping the sites by name when you have this issue?
Do you have root hints enabled in your DNS config?

Cliff GaliherCommented:
As I suspected. The reason I asked for examples and what your examples show is that affected sites are .au sites. And yes, that matters. Here is the fix. While written for SBS 2008, it has been confirmed that this issue exists in 2011 and the fix works.
