server returned a SERVFAIL to a query, would it try the second name server
in its resolv.conf for the same query or would it forward the SERVFAIL
responds back to the application ...

Another question regarding stub resolvers ...

If I have 2 name servers list in my clients resolv.conf file, what is the
timeout algorithm used by the client.  And should I expect the same behavior
for DNS clients from HP, SUN, Linux, MS and ...
