Having problems configuring DNS for Small Business Server!

I have a Small Business Server (2003) set up and running nicely with an SMTP mail feed configured. Currently users can access webmail externally by typing http://ipaddress/exchange . This is all fine but what I'd really like is for them to be able to use webmail.mydomain.com, and also configure 'Outlook Anywhere' (RPC over HTTP)

What DNS settings do I need to configure to allow me to do this without redirecting the www.mydomain.com webhosting towards my SBS server? I just want to have the webmail.mydomain.com for OWA, and to be able to give users the ability to use 'Outlook Anywhere' (RPC over HTTP).

Thanks in advance for any help/advice given!

For your external DNS, configure an host (A) record webmail.mydomain.com pointing to the external IP address.
I'm assuming that your Domain Registrar is hosting your Public DNS. It's often easier to contact your DNS host and tell them what you want to do.  They will often walk you through it over the phone or do it for you.  But the basics of what you need to do is to create an "A" record that does the following.
webmail.mydomain.com  points to Public IP address

You can have multiple records like this that point to different public IP addresses.

Thanks for your speedy reply!

The DNS hosts are incredibly rude and unhelpful.... that's why I'm trying here! :-)

So by creating an 'A' record that would get it as far as my server.... how would I then resolve it to go to the OWA? (.../exchange)?

That can be done in IIS but since this is a SBS server you shouldn't change it for the default website.

You have two options:

1) Let the users log in through RWW or type in the URL manually

or

2) Configure another website on the SBS server, redirect it to something like webmail2.mydomain.com/exchange (or ipaddress/exchange) and configure the web site to only accept a Host Header Value of "webmail.mydomain.com"

Note that you'll need to configure another A record (webmail2) and point it to the same ip address.
How would I do this in IIS?

Just to recap, I have set up an A record that redirects webmail.mydomain.com to http://myipaddress but I want that to actually go to http://myipaddress/exchange.

Thanks for all your help so far!
