This article will go into detail on how to install certificates on Certreq.
This article is for administrators who prefer the command shell.
When your certificate is issued you'll typically receive a file called example_com.cer. Save it on the server and from the same directory run:
certreq -accept example_com.cer
This will install the cert in the Windows certificate store and it will be available to those services and products that make use of the Windows certificate store. These products include but are not limited to: IIS, Exchange, Active Directory (LDAPS), Terminal Services and Microsoft Management Console (MMC).
