In IIS 6 on Server 2003, I can go to a web site's properties and walk through the wizard to generate a new cert request. Once I complete the request and have the cert installed on the web site, I can go into the cert store and export the certificate with the private key, setting a password and saving it as a PFX file.
When I go through a similar procedure in IIS 7 on 2008R2, I can generate the CSR and complete the request. However, the cert in the cert store cannot be exported with the private key and saved as a PFX file. Is there some option or step I am missing in the process so that the private key can be exported in IIS 7?
