RE-RUN SBS 2011 ESSENTIALS WIZARD TO CHANGE DNS

I changed the DNS settings on SBS server and assumed the changes would transfer out to the clients during DHCP renewal, but they don't. I suspect I need to re-run the internet connection wizard, but I can't find the name of the wizard or where it's located. This server has been up and running for six months and without problems.

In an active directory domain, including SBS essentials, the clients should always perform DNS lookups against an AD domain controller (in this case, SBS) and SBS will relay any DNS queries required. So changes you make to SBS DNS won't change anything on the clients. That js by design. That what you are seeing is expected.

I ran an ipconfig /all, on client computers they have two dns servers:  127.0.0.1 and 8.8.8.8. I changed the DNS on the server through the tcpi adapter settings to reflect 127.0.0.1, 208.67.222.222 and 208.67.220.220. How do I get the client computers to reflect this change?

You DON'T.

The server should ON,Y point to itself. No 8.8.8.8...that was wrong, and no new ones that you added. This will BREAK active directory.

As far as the clients go, as long as you used the connect wizard, a small application was I stalled that will properly configure DNS on the client to always point to the server.

When working properly, an IPConfig /all will always show the server (and ONLY the server) as the DNS server on both the server itself and all the clients.

Thus, you are saying SBS 2011 Essentials should be setup like SBS 2003. When that was setup, the only place external DNS sites were listed was in DNS forwarders.

Correct. That isn't just SBS (2003 or 2011) but is core to how Active Directory works, so any domain environment should be set up this way. The SBS wizard doesmthis by default, so the only way that 8.8.8.8 coild have gotten on the adapter settings originally is if someone stepped outside the wizards. ALWAYS a bad idea.

Now, by default, SBS configures the DNS server to use root hints, so you don't even need to use forwarders. And again, this is configured by default so there is rarely a need to step outside the wizards. But if you REALLY want to use another set of DNS servers as forwarders instead of root hints, you will have to do that manually, although I must stress it is rarely necessary and often can cause more issues than it'll solve. I'd only do this if you have a compelling need.
