Issue
IE Enhanced Security Configuration when turned on can display the following message when accessing PowerLink dashboards

The message will display on login and you will be able to continue using PowerLink by clicking close.
Work-Around
To stop this message occurring then the site "about:internet" needs to be added as a trusted site.
Do this using the Add button if available as seen in the above message.
If this button is not available then add this site to Trusted sites zone by opening Internet Explorer: Select the Tools menu, then Internet Options. On the Security tab, select Trusted Zone and then Sites. Now add the site "about:internet".
Resolution
A resolution for this issue is still under investigation.
