When installing an SSL certificate using Microsoft IIS 8.0 Manager, the following error message may occur even though the installation is successful:
This issue occurs because IIS Manager performs a lookup operation for the friendly name of the SSL certificate during the installation. However, the code that performs this lookup operation misses this specific case, and it does not know how to retrieve the friendly name of a certificate in a PKCS#7 file. Therefore, the lookup operation fails, and the error message is displayed.
To resolve this issue, first check to see if the certificate is installed by performing the following steps:
Step 1: Create a 'Certificates' snap-in within the MMC
Step 2: Locate the SSL certificate
On the General tab, under the validity dates, there should be a key with the following message:
"You have a private key that corresponds to this certificate"
Note: If this is present, close the certificate and the MMC and proceed to Step 3. If there is no reference to the key, please follow these instructions to restore the private key: SO21731
If unable to restore the private key, the certificate will need to be replaced.
If the certificate needs to be replaced, please create a new Certificate Signing Request (CSR) on the server by following the instructions in knowledge base article SO21230. Once the new CSR has been created, reissue the certificate using the instructions found in knowledge base article SO5989.
Step 3: Bind the SSL certificate to the web site in IIS
