Running SBS2011
New server about 4 months old
Every 3-4 weeks DNS stop resolving web sites
If I get on a PC and change the Local DNS setting to 8.8.8.8 it works just fine
I tried restarting and clearing out cache on the DNS service and it still does not work.
I don;t see any DNS events
I restated DHCP and DNS started working again
Any suggestions where to start?

The most often cause of this is a known issue with DNS in 2008 and 2008 R2. It is an easy fix.

All machines on the domain including the server must point the server's IP an the ONLY DNS server - don't be tempted to point any machines to the internet either as the preferred or alternate DNS server.

Open the DNS console and make sure that you have a forwarder set to point either to your router or the ISPs designated DNS server - that the ONLY place an external DNS server should EVER be listed.

Cliff is correct and the link he provided should do the trick.

Another temporary fix would be to create a batch file that restarts the DNS Client and Server services on the server at night. Just an idea if the registry change doesn't work.

Adding DNS forwarders to the Forwarders tab of DNS (Admin Tools) also resolves this problem, although it isn't the preferred solution.

Making sure the Windows server is the ONLY DNS server that clients use and adding forwarders is the way to go as I suggested earlier.

Using forwarders is more efficient than relying on root hints.
