How to create a CSR without removing your current certificate in IIS

How to create a CSR in IIS 5.x/6.x without removing the current certificate

Currently the Renew option within IIS 5.x/6.x does not work as intended most of the time. Since IIS does not allow your site that is currently running SSL to generate a Certificate Signing Request (CSR) without removing the existing certificate. For most sites this is not a viable option since the SSL portion of your site would be down until the new certificate was put in place. In order to obtain a certificate for your existing web site you will have to do the following.

Note: You may want to print this page for your records.

(In IIS Admin)

  1. Create a Temporary site within IIS.

    Note: If you're unsure of how to do this step please see the first item in the Related Items section below.

  2. Right-Click on the newly created site and click Properties.
  3. Click the Directory Security tab and then click Server Certificate button.

    (Enter Server Certificate Wizard)

  4. Go through the wizard and enter the exact same information you have on your existing certificate.

    Note: Common Name examples:,, etc.

  5. Send us (Comodo) the CSR.
  6. Install the certificate by proccessing the pending request on the Temporary site created in step 1.

  7. Right-Click on the Production site and click Properties.
  8. Click the Directory Security tab and then click Server Certificate button.

    (Enter Server Certificate Wizard on production website)

  9. Select Replace the current certificate and click Next.
  10. Click Next until you are out of the wizard.

    Note: A typical site is bound to https on port 443 with a unique IP Address.

  11. You may now delete the Temporary Site AFTER you have installed your certificate!
