Hi,
I'm not sure I understand what you mean by "there is no domain associated
with the dedicated server". In the DNS (Domain Name System), each server can
have multiple DNS names.
eg:
www.adopenstatic.com
ns1.adopenstatic.com
mail.adopenstatic.com
are all domain names. They all point to a single physical server. This
*same* server also have the name careers2.careers.unsw.edu.au
Now, all the DNS does is point a domain name to an IP address. So, you
create these by editing the appropriate DNS entries in the appropriate DNS
server. On the IIS server, you need to create your websites, and tell IIS
which websites should respond to requests for what hostname.
Now, if you are using some kind of "web forwarding" service, this might not
work. Web Forwarding has nothing to do with DNS per se. So, host-headers may
work, or they might not. If the web forwarding service does not also forward
the HTTP Host: header that the client (ie browser) sends, then IIS will be
unable to determine which website should answer the incoming request, and
will route the request to a website that does not have a host-header defined
(typically the Default Website)
Cheers

: Thanks, Ken, looks like a pretty good book, must have a closer look at it
:)

: I understand the basic principle of host-headers ok, I've done this before
: with a dedicated server with domain name mydomain.com, individual websites
: set up with site1.com, site2.com, etc. When I forward my sites to
: domainname.com they go to the correct site.

: the site1.com, site2.com to the IP address (as opposed to mydomain.com) -

: suspect that this is because the web forwarding is only passing the IP

: Since the original post, I've found the following on MS
: http://tinyurl.com/2t2rb :
:
: "If the site is used on a private network, the host header can be an
: intranet site name, such as SupIntranet. If the site is used on the
: Internet, the host header must be a publicly available Domain Name System
: (DNS) name, such as support.microsoft.com, and you must register the name
: with an authorized Internet name authority."
:
: So it looks that the dedicated server needs a default domain name, I'm a
bit
: surprised that the host company (ipowerweb) didn't offer this when I was
: buying the package!
:
: I'm wondering if I could get around this with an ASP script on the default
: site or would this be a cumbersome approach? Possibly simpler to get them
to
: set up a domain name for the server.
