I have an SBS 2008 server. In the DNS configuration, should I use forwarders to my WAN router or ISP DNS, or just root hints. If the server is set to use just root hints, does something need to be entered or modified on the Root Hints tab of the DNS server properties, or will it work with the pre-filled FQDNs? I ask because none of the IP addresses for the existing names is listed. They all say "Unknown".
