Operating Systems Linux DNS Response Issue Post 302960746 by hicksd8 on Thursday 19th of November 2015 06:54:06 AM

So is the problem that DNS doesn't work?

If so, why are you talking about ping response from other ip addresses? If those ip addresses exist on your network, then ping responses are no surprise. Why are you connecting the ping responses from 172.30.1.246/7 with DNS servers on 172.30.3.246/7

Are 172.30.1.246/7 the Windows domain controllers?

Do the DNS servers 172.30.3.246/7 work for DNS resolution for the Windows clients?

I am sorry but I still don't understand the issues properly. What happens if you ping the DNS server address(es) from Linux boxes?
