I've got a Windows Server domain controller running DNS on a small network. DNS keeps failing. If you look at the forwarders it shows the IP address and instead of listing the Server FQDN it says <attempting to resolve> or in some cases it gives a simple name like BELINDA. If you unplug the network cable on the back of the server and plug it back in the names immediately resolve and BELINDA becomes 208-91-4-4.wintersbroadband. We're out in the country and my link to the internet is flakey. I suspect I'm losing my internet connection and access to the name servers and that the server doesn't reconnect when the internet comes back up. Unplugging the network cable seems to cause DNS to repair its connection to the name servers.
Would you agree with my diagnosis? Is there a fix that would cause DNS to automatically repair its connection to the forwarders when the network is restored? Note: Internal connections to the server from other computers on my LAN continue to work even though DNS forwarders are down. So, the server is still connected to the LAN - it just appears to be losing its uplink to the internet. I believe the server is running 2008 R2 although I'd have to go back out there to confirm. Thanks for any help you can provide. Curt
