Won't resolve domain but all other DNS servers do

Mine and mindspring's servers say that www.actechnologies.net does not
exist - how can i look up to see what zones that dns server is
serving? Can I do it with the root servers?

How does trace work - does it simply adding more debugging info to my
standard logs?
