Start IIS Manager to generate a CSR on the server where you want to install the SSL certificate. You can do this by opening the Start menu. Select Administrative Tools and then Internet Information Services (IIS) Manager.
Select the appropriate server in the left column and then double click on 'Server Certificates'. Click 'Create Certificate Request' (Actions).
In the next window, you can enter information about your company. The field Common Name must contain the domain name (FQDN) which you want in your SSL certificate. For wildcard certificates, the Common Name must contain a wildcard to the left (for example, *.domene.no)
In the following window, you need to select a cryptographic provider and the length of the private key. The key-length must be 2048 bits or more.
You can now specify where you want to store the certificate request. Click Finish to complete the process.
You can now open the file you created earlier. When ordering a certificate, you need to provide this information (The content includes --- BEGIN and END --- ) to Buypass.
