Certificate errors Windows anniversary update

Hi,

This problem can occur if the client computer's clock is set so that the date/time is later than the expiry date of the web server's SSL certificate.

Resolution

To resolve this issue, an organization that hosts the secure Web site can purchase a certificate for each Web server from a third-party provider. Or, the organization can install a Microsoft Enterprise certification authority in the Active Directory forest.
Then, the organization can use this certification authority to generate a certificate for each Web server.

Note Users of client computers that do not belong to the organization's Active Directory forest can visit the certification authority Web site to download the certificate.
To work around this issue, install the Microsoft Windows Small Business Server 2003 (Windows SBS) self-signed certificate on the client computer. To do this, follow these steps:

• In Windows Internet Explorer, click Continue to this website (not recommended).
  
  A red Address Bar and a certificate warning appear.
• Click the Certificate Error button to open the information window.
• Click View Certificates, and then click Install Certificate.
  
• On the warning message that appears, click Yes to install the certificate.

Thank you.
