Hi all,

When installing a GoDaddy security cert. in SBS 2011 and following their instructions below:

I receive the warning during step #11 saying "The Specified port (443) is being used by a different binding"

Also at step #8 I used "default Website. Is this correct since all I really need to secure is remote logins to for RWW?

To Install SSL Certificates

   1. From the Start menu, select Control Panel, and then select Administrative Tools.
   2. Select Internet Information Services Manager, and click Server Name.
   3. In the Security section, double-click Server Certificates.
   4. From the Actions menu, select Complete Certificate Request...
   5. In the Complete Certificate Request Wizard, enter the location for the certificate file. The file extension might be .txt or .crt instead of .cer (search for all files).
   6. Enter a friendly name for the certificate file, and then click OK.
   7. After the certificate installs, assign it to the correct website in IIS. In the Internet Information Services Manager window, from the Connections menu, select the name of the server where you installed the certificate.
   8. For Sites, select the site to be secured with the SSL certificate.
   9. From the Actions menu, select Bindings...
  10. In the Site Bindings window, click Add...
  11. In the Add Site Binding window:
          * From the Type drop-down menu, select https.
          * From the IP address drop-down menu, select All Unassigned or the IP address of  the        site.
          * For Port, type 443.
  12. From the SSL Certificate drop-down menu, select the SSL certificate you just installed, and then click OK.

Don't use IIS to install a certificate - use Exchange Wizard to request it, then the Wizard to install it.  Their instructions are wrong!

The wizard is under Exchange Management Console> Server Config.

Ignore the GoDaddy instructions. With SBS, *always* use the wizards. The GoDaddy instructions are written for a standalone server that only has IIS. SBS has IIS, Exchange, and RDGateway, which all require the certificate.

Use the "Add Trusted Certificate" wizard in the SBS console to install the certificate, and only use the GoDaddy instructions to install the "intermediate" package (which will not involve IIS or bindings) and you won't have problems.

Hi cgaliher,

I did use the godaddy instructions to install the intermediate cert. I stopped at the bindings error message and then used the "Add a Trusted Certificate Wizard the install the cert. The wizard was very quick.

Is there a way I can test this out on the server?

As long as you've stuck to the wizards, you should be able to browse to from any machine *inside* the network and view the website and the certificate. The wizards set up a split-brain DNS configuration by default, so this will work even if you have not yet configured your firewall.

Hi Cliff,

Thanks for the help with this. i am doing doing most of the prep work offsite then will be setting  up the server on Saturday. I don't think the cert. will be a problem. I have to get back into the SBS way  (Wizards) of doing things. My last 3 server install have been 2008 standard.

Thanks again,
