How to Install a Third Party SSL Certificate on SBS 2003

The following steps outline how to install a third party SSL certificate on your SBS 2003 server. First, you'll need to generate a Certificate Signing Request, or CER. You'll use this to sign up for an SSL certificate and then install the certificate in your server using the IIS Admin console.

  1. Determine the common name for remote access - this is the externally accessible name, eg (hint: this is the same address people use for RWW or Exchange OWA)
  2. Make sure the Administrative contact for that domain has a proper e-mail address that you can access. Usually This email address is being protected from spambots. You need JavaScript enabled to view it.
  3. Open the Server Management console
  4. Go to Advanced Management > Internet Information Services > [your server] > Web-Sites > Default Web-Site
  5. Right click on Default Web-Site and select Properties
  6. Open the Directory Security tab and select Server Certificate
  7. Click Next and select "Remove the Current Certificate", then follow the prompts to remove the certificate
  8. Go back into the Server Certificate option and select "Create New Certificate"
  9. Select "Prepare the Request Now, but send it later" and click Next
  10. Enter you Organization Name (your Company name) and Organizational Unit. Record these details in case you are quizzed by the CA later.
  11. Enter the sites common name -
  12. Click Next and fill in the required Geographic Information
  13. Save the request to a file
This will generate a CSR file, or Certificate Signing Request. Open this file in Notepad and copy the information to the clipboard.
Apply for an SSL certificate (you can get one at!) and enter the CSR. Several emails will be received by the Administrative Contact, there will be two important ones - a confirmation that you must click on, and then the certificate itself. Save the certificate to the server with a filetype extension of .cer
To install the certificate on your server:
  1. Open the Server Management console
  2. Click Internet and E-Mail
  3. Click Connect to the Internet
  4. On the Welcome page, click Next
  5. On the Connection Type page, click Do not change connection type, and click Next
  6. On the Firewall page, click Do not change firewall configuration, and click Next
  7. On the Web Server Certificate page, click Use a Web server certificate from a trusted authority, and click Browse
  8. Select the certificate.cer file you saved earlier, and click Next
  9. On the Internet E-Mail page, click No not change Internet e-mail configuration, and click Next
  10. On the Completing the Configure E-mail and Internet Connection Wizard page, click Finish
