Exporting certificate from IIS - not able to save .pfx

I have all together 3 certificates on a windows 2003 server (IIS6) which I have only been able to export 2 out of the 3 successfully as a .pfx file, allowing me to import onto our new webserver.

On the old server, the 1 that I'm not able to export as a .pfx file is not giving me the options to export the private key, and it won't let me save it as a PFX file.

It only allows me to save as .CER or a P7B.

When attempting to import into IIS, there's no option to import these kinds of files - how can I get this certificate installed and available to IIS on the new machine?

Are you using the certificate MMC plugin to export the certificate?there you have the option to import either in P7B or PFX format
If you cannot export the private key it is because when the certificate was first installed the private key was marked as not exportable.

PFX is a format that can include bth a certificate and a private key, but if you can't export the private key it won't ley you use PFX since there is no benefit to storing just a certificate as a PFX rather than as a CER file.

The way you get a CER file on a machine is to use the Certificates MMC to import the CER file, but if you don't have a private key to go with it it wil be useless as far as IIS is concerned.

You will either need to find a different copy of the certificate that *does* have the private key or you will need to request a new certificate.
