Question : MS DNS Server - need to resolve all domains to one iternal IP address

Background:
I have a basic NAC solution in place that ties into our MS DHCP server & utilizes an installed client on the workstations.  When an unknown computer (w/o the client) attaches to the network, they get a 255.255.255.255 mask.  They're blocked, it works great.

I would like a way to redirect the web browsers on those unknown computers to a local Intranet page that explains why they're blocked, who to call and so on.  My NAC guy told me to set up a new DNS server that resolves all DNS names to the same IP address.  That IP address being my intranet server.  Then in my DHCP options I would setup the DNS option for the unknown computers to point to that new DNS server.

Does anyone know how to accomplish this with a Microsoft DNS server OR is there another way of achieving the redirect that I want without spending gobs of money?

You're on the right lines there :)

Add a root zone, a zone called "." to the DNS server in question. Then create a wildcard record (*) in that zone pointing at the IP you want.
