How to Add/Install a SSL Certificate to a Site in IIS 6 (Dedicated/VPS)

This article assumes that you have already created CSR, sent it to your Certificate Authority, and have received your SSL certificate file. If you need to create a CSR, read Knowledge Base Article #1584 for instructions. 

NOTE: We offer Trustwave SSL certificates at a discount. For Trustwave certs, you will receive an email from them when your certificate is issued. This email will include a ZIP file. The only file you will need for the installation ends in .p7b. You will need to transfer the .p7b file to your server. 

1.  Once logged into your server, open the IIS Manager.  You can do this by clicking your Windows Start button and entering "inetmgr" into the search box.  Then, press enter.

2. Right click on the website where you previously created the CSR and choose "Properties."

3. Click the "Directory Security" tab and then click "Server Certificate" in the "Secure Communications" section.

4. When the wizard starts, choose "Process the pending request and install the certificate" and click "Next."

5. On the next screen, click "Browse" and then click the drop down box to choose "All Files *.*"

6. Next, navigate to the folder where you stored the certificate file from your CA (with Trustwave, it is named .p7b) and select it. Click "OK" and then click "Next." 

7. Verify that the port number is correct. The default SSL port is 443.

Close the wizard, and your certificate will now be installed. In most situations, IIS will instantly begin using your SSL certificate. The best way to test your certificate is to open an Internet browser and visit your website's secure URL ( or, where "" is your domain name or the common name that was used for generating the CSR).
