DNS is not reachable- how do I resolve it?

Hi,
I just got a new system with Vista business and I need to run intranet
websites on it using IIS. when it tries to browse a website as a server, it
gives me this error:
"DNS is not reachable"
it can't see 127.0.0.1.

it is different from xp pro.
I don't know how to set up the IIS or something else to resolve it.
I appreciate any help.

Sounds like DNS issue. How do you setup DNS?
