I have an SBS 2011 server running at one of our 2 sites. The sites are linked together through a site-2-site VPN using Cisco RV042. At the remote site, I have an RODC and backup DNS running on W2K8 R2 server.
DNS seems to run fine from both locations except I can't reach our own website (www.ownwebsite.com
). The website is remotely hosted and accessible from any other Internet access outside our network. We also use remote.ownwebsite.com and that works fine for OWA and RWW.
If I do nslookup for any website other than ours, I get a quick response. In the response, I see server name "unknown" with the IPv6 address of my NIC card. If I do nslookup for www.ownwebsite.com
, I get "DNS request Timed out" and "Request to unknown Timed-out". If I restart the DNS server a couple times and delete the cache, the DNS lookup will work for a while but quickly stops working.
