Web servers that support the Secure Sockets Layer protocol present a digital certificate verifying server identity to Web browsers that request connection. Windows Internet Explorer will display a certificate error notification if the digital certificate cannot be verified by a third-party certificate authority or if the date and time of the certificate are not correct. Resolve the error by correcting the Windows system date and time or install the digital certificate if the server is using a “self signed” certificate.
