selecting which DNS forwarder to use

G

Guest

We are trying to get to a web site that we cannot get to with one DNS
forwarder but we can if we use the 2nd DNS forwarder. Is there a way to tell
DNS to use the 2nd DNS forwarder only if we are trying to get to that one
specific web site ? Is there a better way of doing this ?

Thanks

No, forwarders are typically used in ORDER but the first one
to respond is used (even if it is a "negative" response -- i.e.,
NOT FOUND.)

Even so, the second may get used first if it is consistently faster.

Either stop using the broken forwarder, or get the problem resolved
between the forwarder and the owner of the domain.

You could also hold the record locally for that ONE WEB SITE
if you are willing to take responsibility for keeping the records up to
date.

The method for this latter is to create a ZONE for the SAME NAME
as the web site, e.g., www.troublezone.com would be the ZONE NAME.
The WHOLE thing including www would be the zone you would create.
Then add a blank (no extra client name) to the zone with the correct IP.

Notice you do NOT create the REAL zone the web server lives in (e.g.,
don't create troublezone.com) but the a zone with the same name as the
server.

Conditional forwarding, available on Windows Server 2003.
