I am trying to get RPC /HTTP running on SBS 2003. I have installed a SSL cert from Go Daddy and OWA https works perfectly. However, I am unable to get Outlook to connect.

I have followed the setup procedures on http://www.petri.co.il/how-can-i-configure-rpc-over-https-on-exchange-2003-single-server-scenario.htm.

entering https://fully.qualified.domain.name/RPC into my web browser on a different LAN returns a username and password box. However, it never accepts the username/password combo.

Here are my test results.
      Testing RPC/HTTP connectivity.
       The RPC/HTTP test failed.
       
      Test Steps
       
      Attempting to resolve the host name owa.bhfitness.com.au in DNS.
       The host name resolved successfully.
       
      Additional Details
      Testing TCP port 443 on host owa.domain.com.au to ensure it's listening and open.
       The port was opened successfully.
      Testing the SSL certificate to make sure it's valid.
       The certificate passed all validation requirements.
       
      Test Steps
      Checking the IIS configuration for client certificate authentication.
       Client certificate authentication wasn't detected.
       
      Additional Details
       Accept/Require Client Certificates isn't configured.
      Testing HTTP Authentication Methods for URL https://owa.domain.com.au/rpc/rpcproxy.dll.
       The HTTP authentication test failed.
       
      Additional Details
       Exception details:

Type: System.Net.WebException

The link you provided notes at the top (2nd paragraph) that the procedure is not required for SBS, as it is already properly configured.  You can skip to the section "Configure the Outlook 2003 computer to use RPC over HTTP/S" at end, or straight to the article it refers to.

One thing I did not see in the article is that you need to make sure you install the certificate on each computer to get things working.

I followed the instructions on the site and have had no success in getting Outlook to connect to Exchange. Is this becuase the certificate was not installed on the client computers? How is the cert installed on the client computer, in this case Win 7 running Outlook 2003.
The low tech way that I've been getting certificates on machines is by going to OWA or RWW, and viewing the certificate (clicking or double-clicking the lock).  There will be an option to install the certificate, which will launch wizard.  Take defaults.  

Microsoft has article on importing/exporting certificates on Windows 7 here.
