Create self-signed certificates for each site requiring Server Name Indication

The SelfSSL tool is installed with IIS, and allows you to create self-signed certificates that include the ID of the site within the certificate.

1. In the Internet Information Services (IIS) Manager, click Sites and make note of the ID of each website using the self-signed certificate that has Requires Server Name Indication selected.
2. Open a command prompt and navigate to C:\Program File (x86)\IIS Resources\SelfSSL.

3. At the prompt type the parameters for the certificate, ensuring you specify the site ID for the site requiring Server Name Indication. For example:

   	Note: In the command, /V is the number of days the certificate is valid, /S is the ID of the site. Use the values that correspond to your site in the command.

   selfssl.exe /N:CN=TEST.SITE.3 /K:1024 /V:<days-valid> /S:<site-ID> /P:443

   The certificate is created.

4. When prompted to replace the SSL settings for the site, type Y.

5. Modify the site to use the new certificate in the bindings. See Identify the certificate to be used by each website.
