When you attempt to access a Web page that is hosted by IIS (Internet Information Services) and is configured to use SSL (Secure Sockets Layer) by using the HTTPS protocol, you receive:

Page cannot be displayed.

The Web server's event log contains:

Event Type: Error
Event Source: Schannel
Event Category: None
Event ID: 36869
Date: MM.DD.YYYY
Time: HH:MM:SS
User: N/A
Computer: <ServerName>
Description: The SSL server credential's certificate does not have a private key information property attached to it. This most often occurs when a certificate is backed up incorrectly and then later restored. This message can also indicate a certificate enrollment failure.

This behavior occurs because the Web site has been bound to a certificate that doesn't have a matching private key. When you attempt to export this certificate using the Certificates MMC, there is no option to export the private key. When you export the certificate, you receive a You DON'T have a private key that corresponds to this certificate warning.

To resolve this behavior:

1. Remove the current certificate that does not have a private key.

2. Install a new certificate with private key.

NOTE: See How to assign a private key to a new certificate after you use the Certificates snap-in to delete the original certificate in Internet Information Services.

NOTE: See SSL Diagnostics tool.
