new sites (domain) seem wo work yet redirect to host (bluehost) landing page

we’ve had an existing install (root directory) up and running for a few years – and recently activated multisite – think we followed all of the directions (used Andrea’s PDF) – can now see the admin in the backend but when setting up a new site (domain based) the site just redirects to our host’s not found landing page
– site is golfscene.ca and, for example, i have a new site biz.golfscene.ca set internally – i contacted the host and they say that everything that they handle works and that it is a wordpress install issue?
