We have a Small Business Server 2008 with DNS setup. Our domain name uses .com instead of .local. That's the way it was when I got here and I just migrated it from SBS 03 to SBS 08. It has 2 forward lookup zones, our domain name and our domain name with the prefix of remote for exchange.
Under our domain name zone there are two grey icons for the NS records, one for remote and one for www. Remote points to our own server. www pointed to our external name servers for web hosting. We were using SiteServer for our web hosting, but I've moved our website to PowerDNN. The new website was working for everyone except our internal network. So I changed the www records from pointing to SiteServers name servers to PowerDNNs name servers, but now we just get a 404 error when attempting to hit our website. If I ping our web address internally, it points to our SBS server. I've tried changing the NS records back to SiteServer and then it works again, but points to our old website. Once I change it back to PowerDNN, it points us back to our SBS box.
I've already been through several forums and checked the normal things like hosts files, and clearing both the client and server cache. There is only one entry in the host file and it points to 127.0.0.1 It just seems to not be able to see the PowerDNN name servers even though it validates the FQDN to the IP address and gives me the green check.
