Details

The ability to access data zones across domains could cause the user to unknowingly access content hosted on an unauthorized server. Access to data sources across multiple domains must be controlled based upon the site being browsed. This policy setting allows you to manage whether Internet Explorer can access data from another security zone using the Microsoft XML Parser (MSXML) or ActiveX Data Objects (ADO).

Solution

Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Internet Zone -> ‘Access data sources across domains’ to ‘Enabled’ and select ‘Disable’ from the drop-down box.
