Hi,
Please perform the following steps.
This error message appears because the security certificate was issued by the University itself and not by an authority acknowledged by Microsoft.
To solve this problem, for most webpages you just have to install the "CA Certificate" of Ghent University in your browser.
For certain websites, such as https://zephyr.ugent.be, you need to import its own certificate:
Click on "Certificate Error" next to the IE7 address bar and then "View certificates"
Click on "Install certificate..."
Click "Next"
You will be asked where the certificate has to be stored. You can use the default setting and click "Next".
Click "Finish"
Confirm by clicking "Yes"
On your next visit, you will not see the error message again. Hopefully it should work.. Thank you
