SYMPTOMS

When you attempt to browse to a secure Web site, you may receive the following error message:
Client certificate has expired or is not yet valid.

CAUSE

This behavior can occur if the date or time settings on your computer are incorrect.

RESOLUTION

To resolve this issue, follow these steps:
  1. On the Apple menu, point to Control Panels, and then click Date & Time.
  2. Verify that the date and time on your computer are correct. If not, adjust the date and time settings as necessary.

  4. Start Internet Explorer, and then attempt to browse to a secure Web site.
