Main DNS server not resolving
Posted on 2013-06-10
After a power outage this weekend, we have discovered that the main DNS server is not resolving. Any computer set to statically query this server cannot reach the internet. Any DHCP is fine. We use an external DNS server as a web-blocker...anyone connected directly to this site works fine.
Any computer set to DHCP connects to internet.
Any computer statically set to our extennal DNS (OpenDNS - 188.8.131.52) connects to internet.
Any computer statically set to internal DNS (domain controller with Windows 2008 R2) will not connect to internet. Cannot ping google.com. Cannot reach google.com.
Our internal DNS is supposed to forward all requests to 184.108.40.206 - but I am unsure how to check this. Where should I look in DNS manager? Any other tests I can run?
Thanks in advance.
