I have a T1 provided by WilTel. With it, they give me two DNS servers that I use a my primary and secondary name servers. I also have the DNS set up on my server. My clients use it as their primary name server.
About noon yesterday, something weird happened. At this point, when I do "dig" inquiries on the server, I get back something that I have pasted at the bottom of this note.
It appears to me as if the local resolver on my server will not process an iterative request. i.e. when the lookup for a.b.com returns the servers for .com, it does not repeat the request to the .com servers but just returns the list of .com servers.
I can't tell if this is a local problem or if this is a problem with WilTel's name server.
Can anyone help me?
Thank you,
pedz
