Hi Guys,

This question isnt specific to W2003 but.. Im trying to run an application on a server, 
the application accepts connections on a single IP but uses the hostname to distinguish 
which service to direct to.

The root domain for the services is like this: service.domain.com

But i want to give each person a "sub domain" of that address to access their service. 
Like this..

one.service.domain.com
two.service.domain.com
three.service.domain.com

But, the IP of each "sub sub" domain, returns the IP of domain.com and not service.domain.com.

Instead, all subdomains of service.domain.com should have the same IP as service.domain.com 
and NOT the root IP of domain.com

Hopefully I've explained that OK.
I've googled around but its hard to find a document that means what im looking for.

Thanks in advance

What happens is that you have a default (wildcard) entry, and everything in front 
of service.domain.com falls under that wildcard, which is usually pointed at the 
root domain  (domain.com)..

So.. Say, if I do a DNS lookup of abc.domain.com and abc is not in my DNS server 
records, it will return the wildcard address which is domain.com.  If I do a DNS 
lookup of abc.services.domain.com and abc.services.domain.com does not exist, I will 
fall under the wildcard entry for domain.com.

I think the way to properly handle this, is to create a new zone in your DNS server.. 
 That zone will have a root domain of services.domain.com, then create a wildcard 
entry for that zone that points to services.domain.com.  Then, no matter what you 
type in front of services.domain.com will point to the proper location.

I believe wildcards can be placed in Windows server 2003 DNS just by using the * 
symbol.  So, a *.services.domain.com A record that points to the IP address of services.domain.com 
should do the trick.

Either that, or you just create a new wildcard entry in your root domain (*.domain.com) 
and make it point to services.domain.com.. However, this would not be considered 
standard practice as most people want misspelling and such to point to the root domain. 
So, if I am trying to get to your website and I accidentally type wew.domain.com 
it will go to domain.com anyways and display the proper webpage.

Hope that helps.
