Hi,

I'm an absolute beginner here, so please bare with me.
Is it possible to configure a primary Microsoft DNS server in our local
domain so that when it first receive a Local DNS resolution query from
a web browser,
1. it would forward request to our root server.
2. If our root server could not find it, it will bounce back to our
primary DNS server so that the primary DNS server could use wildcards
to return the IP address of our IIS server to display an error page.

cheers,

Lim

What you are wanting to do won't work with a wildcard.

If the DNS client finds a wildcard in its searched suffixes, if there are no
closer matches, and will not forward the request in the first place.
You would have to create a custom error in Internet Explorer that would make
IE use the custom page in the event the DNS lookup fails.
If you used a wildcard, any record not existing in your DNS server would use
the wildcard. This is simular to what happens if you have a wildcard record
in a searched DNS suffix in the DNS suffix search list.
