Environment
Internet Information Services

Cause
Users with Windows servers may occasionally encounter an issue when an imported certificate disappears from the list of server certificates. Most often, this happens right after completing certificate request in Internet Information Services (IIS) Manager and refreshing the list of certificates.

The lists of server certificates in IIS contain only certificates that are assigned to the corresponding private key and generated along with the certificate signing request (CSR) used for activating a particular certificate. When the link between the certificate and the private key is broken for some reason, the certificate disappears.

Resolution
In order to make the certificate reappear, you will need to force the link between the certificate and the private key using the following steps:

1. Locate the certificate that was imported when completing certificate request.
2. Double-click the certificate and go to the Detailstab.
3. In certificate details locate the Serial Number field, click on it and copy its value. Note: Make sure any space in the serial number is removed. It should be a single string of symbols.
4. Open Command Prompt.
5. In the command prompt type: certutil -repairstore my SerialNumber

6. The certificate should appear in IIS manager once the list is refreshed.
