'The current Web page is trying to open a site in your Trusted sites list'

This message is most likely to occur for users browsing the Internet with IE v7, after IE security updates have been applied that change the Internet, Local Intranet, and Trusted zone settings. For example, customers may see the following message when using Transparent-Mode Auto-Login:

Note: If using DNS Auto-Login, the "Trusted site:" value will be the iPrism hostname instead of IP address.  

The message above does not prevent Internet access, but may be annoying to users. Users may simply reset IE to default security settings using "Reset all zones to default level".

Alternatively, you may also check the following setting as a means of resolving the messaging.

In IE v7, go to Tools > Internet Options > Security > select Trusted Sites > click Custom Level to view the browser settings. "Websites in less privileged web content zone ..." could be set to "prompt".  You may want to change the setting to enable or disable instead.
