Installing an Intermediate CA Certificate in Windows

When downloading an SSL certificate from a Certificate Authority (CA) , the CA will generally include a separate Intermediate CA certificate which also needs to be installed on the server.

Installing the certificate is pretty straightforward, except that Windows does not include a Certificates console in the Administrative Tools folder.  So, you’ll have to create that one yourself.

1. Right-click on the Windows icon and select “Run”

    Start Menu

2. In the “Run” box, type “mmc” and hit <ENTER>


3. When the MMC console is up, hit <CTRL>+M and the Add Snap-Ins window appears


4. In the left pane of the “Add or Remove Snap-ins” Window, select “Certificates”, and click on “Add”

That’s it!  The certificate is now installed in your Windows server.  This is the procedure you follow for installing certificates in Windows, regardless of where you get them.

I hope this has helped someone out there!  As always, your feedback is welcome.
