Appearantly Small Business Server insists on using remote.yourcompany.com for the virtual directories/connection points for Exchange, OWA and Remote Workplace.
However, if my trusted SSL certificate is issued to say secure.yourcompany.com the users will be hassled with security prompts warning of the mismatch.
Can this default be easily changed to match the SSL certificate?
I'm thinking that you should be able to change this using the Advanced option in the Internet Domain Name settings in the SBS console. Open the console, select the Connectivity tab, select your Internet Domain Name, click the Set up your Internet address link and select the manual setup options in the wizard and then select the Advanced options to change the name from remote to secure.
Also, make sure you have the correct SSL certificate installed after you make the change.
I can't recall exactly, but there's a point in the setup wizard/checklist where it asks you for your domain and there's an Advanced button you can click to change the sub-domain. This should be set to whatever you had for your certificate. Obviously you'll need to export/import your existing certificate, but this will set IIS/Exchange for Remote Web Workplace purposes.
It's also recommended that you use the setup checklist/wizard for your initial setup: there's alot of "behind the scenes" stuff with SBS 2008/2011 that doesn't get initialized when using tools like dsa.msc, etc. to make changes.
Allthough SBS is already using a single hostname/certificate, the script in this blog post proved most usefull, as it sets all the virtual directories to a common name.
