Re: [Efw-user] Can ping dns server in Green, but cannot dig it from endian 2.5.1 box
Is your internal DNS server authoritative for myserver.mydomain.org? What is the error that dig returns?

Very strange.. what about looking up other domains through the same method?

What dns servers are defined under /etc/resolv.conf?
