This means that the DNS server is the router, essentially skipping the SBS name resolution step. Clients *also* get their IP and DNS Server from the DHCP server, which in Essentials, by default, is the router. This means that if the server were to ask for an Internet based address, like, it would forward that request to the router, which would intern forward it to the ISP, which could hopefully resolve it for you.Ĭlients on the network also still need to use the SBS DNS Server in order for Active Directory to work, or to resolve the server and other services on the network (for example, client backup doesn’t work unless DNS is operating correctly). Routers by default will hand out their own IP as the DNS Server and proxy DNS out to the WAN configured (usually DHCP but sometimes services like OpenDNS) DNS servers. If you dig into the DNS settings, you’ll notice that the DNS Server picks up the routers IP as a forwarder. It does however use its local DNS server to resolve both local and Internet based names by overriding the DHCP assigned IP address to 127.0.0.1 (localhost). Essentials will automatically connect to the Internet just like any client computer, using the DHCP assigned address. SBS 2011 Essentials doesn’t assign itself a static IP address, and it doesn’t have a Connect to the Internet Wizard. Ultimately SBS is a middle man in the peer to peer DNS infrastructure and gives the full power of DNS to the local network
Internet based addresses (such as ) are first sent to the SBS box for resolution, and then forwarded on to the ISPs DNS servers for name resolution. DNS works flawlessly in such an environment. Since SBS 2008 and SBS 2011 are DHCP servers by default, that means they hand out IP addresses, and the server’s IP as the DNS server. Then as we all know, the DNS server runs on SBS and resolves local network addresses, like “domain.local” or “server” or the internal fully qualified domain (FQDN) “”
With the SBS 2008 and SBS 2011 the Connect to the Internet Wizard would analyze your network and determine a static IP address to use, and then ensure you like it before making it the server’s IP address. If you’ve used Windows Small Business Server in the past, you’ve probably figured out exactly how DNS works.
