Secondary DNS: Depends on Primary?

[Guest]

Hi all,

My primary DNS server failed the other day and, to my surprise, our
secondary DNS server stopped serving DNS queries soon after. Apparently, it
was not storing local copies of the DNS records? Does this mean I should
select "File" storage instead of "Active Directory and Registry?" Any other
recommendations for secondaries I should know about before our primary fails
again?

Thank you!!!

You need to clarify this because there are only primary and secondary zones,
not primary and secondary DNS servers. One DNS server should not depend on
another DNS server unless it is forwarding to it and you probably shouldn't
be doing that.
If the secondary zone failed shortly after the primary, what is the expire
time on the zone?
The default expire time on MS DNS is one day, which in my oppinion, is too
short.

Curious, how was it determined the server failed? At this point it would
help with some extra info. Can you describe the syptoms, were there errors
regarding resolution, and what Event log errors do you see? Are you also
indicating the zone disappeared from DNS?

I would usually leave those settings default. I haven't needed to change
that in any of my clients' systems.
