Windows - Importing SSL Certs In IIS

First, you need to be able to import the file into MMC. Most of these instrucions are from microsoft at the following url:

  1. Click Start, point to Run, type cmd, and then click OK.
  2. Navigate to the directory where Certutil.exe is stored; by default, this is %windir%\system32.
  3. Type the following command at the command prompt:
    ertutil -addstore my certnew.cer
  4. Where certnew.cer is the name of the certificate you received from the certification authority (CA). You should see the following message:
    CertUtil: -addstore command completed successfully.
  5. Navigate to the directory where you stored the certificate you received from the CA. Double-click the certificate to view the certificate properties.
  6. Click the Details tab and select <All> in the Show drop-down list.
  7. In the Field list, select Thumbprint to display its value in the view pane.
  8. Select the Thumbprint value in the view pane and then click CTRL+C.
  9. Return to the command prompt window and type the following command:
    certutil -repairstore my "thumbprint"
  10. Where thumbprint is the value of the Thumbprint field. Be sure to type the double quotes as part of the command. If the command is successful, the following message is displayed:
    "Encryption test passed CertUtil: = repairstore command completed successfully."

Once this is complete, you may need to select the .cer file in MMC, and export it as a .pfx. Once you have the .pfx you will need to import the file in MMC, then you an add the cert to the domain in IIS.
