This behavior occurs if the computer name does not match the name that is specified as the common name in the SSL certificate. For example, this behavior occurs if the computer name is a NetBIOS name and the SSL certificate uses a fully qualified domain name (FQDN).

To resolve this behavior, verify that the following conditions are true:

•The computer name and the name that is specified as the common name in the SSL certificate are both NetBIOS names or both FQDN names.

•The SSL certificate has not expired.

•The Web server trusts the certificate or the certificate issuer.

•The certificate is not corrupted.

•No one has tampered with the certificate.

•The Web browser on the client computer recognizes the format of the certificate.

•The Web browser on the client computer can read the certificate.

•The SSL certificate has not been revoked.
