After you configure a Microsoft Windows Server 2003-based terminal server, standard users cannot turn off the Internet Explorer Enhanced Security Configuration feature. When a standard user clicks to clear the Internet Explorer Enhanced Security Configuration check box, the check box remains clear as expected. However, Internet Explorer Enhanced Security Configuration is still enabled.
Note You are more likely to experience this behavior on a terminal server that you configured from a prepared image (Sysprepped image).
To resolve this problem, use one or more of the following methods, as appropriate for your situation.
Method 1: Rebuild the terminal serverIf the terminal server was configured to have Internet Explorer Enhanced Security Configuration enabled and if the terminal server is in a locked down environment, you may be unable to completely remove Internet Explorer Enhanced Security Configuration.
In this case, it may be quicker to rebuild the terminal server. When you do this, use an Unattend.txt file together with the Windows Setup program to disable Internet Explorer Enhanced Security Configuration during the installation of Windows.
