Open File - Security Warning
I've just setup a Windows 2008 R2 server dealing with XP clients. I've redirected the desktop to a DFS share and implemented a GPO to lockdown the workstation for the students. When they double-click an icon on the desktop they get a Security Warning asking if they're sure they want to open it, and the publisher isn't verified. I've done some googling and it appears to be down to IE settings, and I can find how to alter it on Server 2003 GPO, but not on 2008 R2 as the Internet Explorer settings have changed in group policy. Can anyone help please?
