Redirect OWA 2003 – HowTo

Primary objective – I would like to know how to have users access mail by typing in webmail.domain.com instead of www.domain.com/exchange, which is how they access it right now.

Secondary objective – I would also like to implement SSL on it.

Background info:

I am using Windows Server 2003 standard, Exchange 2003 sp1, and IIS 6. All roles are on one machine. I currently have a CNAME record for www.domain.com, and I also have an MX record pointing to my mail server.

Thanks for the help!
