SSL certificate renewal issue - missing private key

Hi all,
I'm having issue to renew the existing website certificate with new algorithm (from SHA-1 to SHA-256).

1. Tried to renew existing certificate (hostname1) and received error 4824 - Invalid Subject Alternative Name (SAN) or Common Name (CN)

2. Created a new CSR that contains the same information and enrolled a new SSL certificate with FQDN hostname1.domain.com. However, once it has been installed we received private key missing error.

3. Tried to recover the private key using certutil command but failed with error  "The Smart card resource manager is not running".

What is the process to renew the existing certificate (hostname1) with updated algorithm? (from SHA-1 to SHA-256 with RSA Encryption)

Is this a web certificate?

Use iis, create a new site, use generate the CSr, edit it to add the SAN items. Submit the CSR for signing, complete the certificate on IIS, export the certificate and private key and load it on the site/sites to which they serve.
