I'm running two servers, both 2003 R2 one is a
(A) File and Print server 192.168.1.100
(B) AD, DNS, DHCP 192.168.1.2
Gateway is 192.168.1.1
Server A is also a backup DNS server.
We had a power cut over xmas and I have been having issues with DNS ever since.
Server A is fine. It's pointing to itself for DNS, and I can ping loopback, gateway, external.
Server B is the problem. This is the primary DNS server on our network, and is having connectivity issues. Cannot ping the gateway, or anything external, but can ping internal machines. Recursive queries are failing in tests, and nslookup is saying ''Can't find server name for address 192.168.1.2''.
I have tried opendns to get out, but no luck. Can anyone suggest some troubleshooting steps to get this sorted?
