Sorry if this is a duplicate question, but I didn't see anything like my problem. This is also my first time renewing a cert.
So, a bit of backstory. We have a sharepoint site, with a ISA firewall doing web traffic redirection. Our Sharepoint server is not public facing, so we have a cert for a web listener installed to use SSL on incoming traffic, so when people log in, their passwords are not in clear text.
Based on the instructions on the seller's website, you have to generate the Cert Request from the IIS box (sharepoint) but install the cert on ISA (firewall) OK, so far so good.
I am able to export the cert, import it into the computers personal cert store. However when I go to the listener rule on ISA, the new cert is not showing up as valid, it says the private key is invalid or missing.
So here is where I made a mistake somewhere. According to KB 292569
"If you do not have the option to click Yes on the Export Private Keys window, the private key has already been exported to another computer or the key never existed on this computer. You cannot use this certificate on ISA Server. You must request a new certificate for this site for ISA Server."
The cert from the seller, when I right click to export it, doesn't have a option to include the private key.
So according to the MS article, do I need to start over with a new CSR?
What did i miss to cause my cert to not have a private key?
