Configuring third level domain (DNS)

You can do this a couple of ways, depending if you run your own dns. I am assuming that you are, and it is windows dns. If you want only one record, you can just create an A record(Host record) for support.mydomain.com and a www.support.mydomain.com and use a host header on the web page to have it come in. If your mail server is going to be the same for mydomain.com and support.mydomain.com, you dont have to do a thing. If it is different, you may have to add a MX record for support.mydomain.com to point to the right mail server. If you have more then one record, you can create a new dns zone, support.mydomain.com and in mydomain.com create a new NS record and point it to your support.mydomain.com. This is delegated. Both work. Its hard to explain, let me know I can send you a few pictures if necessary

Thanks. You've assuming well. I'm running Windows 2000 with its DNS. The site is configured with IIS 5. Unfortunately I've tried a couple of times, but doesn't works. Since i'm not so confident with DNS, could you please help me with some pictures of the procedure (should be explained better than thousand words).

I know I have not contributed to the discussion but I am trying to do something similar and would love to have any of the documentation that is provided to the original poster. If you would like you could email it to me at jlbpotter@hotmail.com. Thanks.
