📋 Table of Contents
A Windows 7 computer is experiencing an error with expired SSL certificates, specifically with the domain contoso.com. The issue affects all users on this computer, regardless of browser used, but not on other Win 7 computers or when using a different operating system such as Ubuntu.
This problem can be frustrating for users who rely on secure connections to access websites. In this guide, we will walk through the steps to troubleshoot and potentially fix this issue.
🛑 Root Causes of the Error
- The primary reason for this error is that the computer's Windows 7 operating system is not properly handling the expired SSL certificate. This can be due to a variety of factors, including an outdated version of the Windows Security Updates or incorrect configuration of the Trusted Root Certification Authorities.
- Alternatively, it is possible that there is a conflict between the existing certificates on the computer and the new certificate from GeoTrust Global CA.
