Are you getting this error when trying to connect to a site/domain/service and then you checked your router/nameserver's logs to see what's wrong?
You may see something like this:
named[3025898]: REFUSED unexpected RCODE resolving
This is not usually an error with named or bind, at least not on your end but NORMALLY this is an issue with the remote nameserver.
A lot of times this is a misconfigured remote nameserver. A classic case may be that the remote nameserver is up but the zonefile is non-existent or misconfigured or even hacked.
You should contact the domain admin e-mail of the remote side to see what is happening.
