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 (  The website is remotely hosted and accessible from any other Internet access outside our network.  We also use 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, 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.

Any ideas?
