Certificate Installation: Microsoft IIS 5.x & 6.x
Installing a certificate on Microsoft IIS 5.x / 6.x
You will need a Dedicated IP for the SSL domain. You cannot install the SSL on to a IP where are more then one domains!
You will have received your certificate file from us, usually named 'your_domain_com.cer'. Alternatively, you may have received it as several files: 'your_domain_com.crt' and Ca Bundle [download the Ca Bundle]
If you received a single file with a .cer extension, you only need follow the first half of the instructions. Otherwise, please follow the instructions completely.
Copy the file(s) you received to the server.
- Log in to the server. Go to 'Control Panel' > 'Administrative Tools' and double-click 'Internet Services Manager'.
- Right-click on the website you wish to install the certificate on, and select 'Properties'. From the window that appears, click the 'Directory Security' tab.
- Click the 'Server Certificate' button to begin the Certificate Wizard. Select the option 'Process the pending request and install the certificate'. Click 'Next'.
- Browse to the location of the certificate file. This is the file with your domain name within the filename. Click 'Next'.
