Disable Internet Explorer Enhanced Security Configuration

April 10, 2010 | Filed under Internet Explorer


On Windows 2008, by default the Internet Explorer is totally unusable in the sense that everything is restricted. You cannot view web pages with flash, you cannot download files, and many other things you cannot do which makes you think that it is only possible to visit a clean HTML page that doesn’t require plugins. When you open Internet Explorer, the first thing you see is a link that points to res://iesetup.dll/HardUser.htm and the page says “Internet Explorer Enhanced Security Configuration is enabled. Your server administrator has applied enhanced security settings to Internet Explorer. These security settings might prevent you from accessing certain Web sites and network resources, or performing other browser operations, such as downloading files. If you trust a Web site and need it to be functional, you can add the Web site to the Trusted Sites zone.”

Disable Internet Explorer Enhanced Security Configuration

Weirdly after adding the site to the Trusted Sites zone, the website is still inaccessible. The only solution that worked for us is to disable the IE Enhanced Security Configuration. The steps below shows how to do that:

1. Run Server Manager from the Quick Launch bar. If you can’t find it, type ServerManager.msc in the Run window and click OK.

2. At the Server Manager main window, there are 4 categories on the right pane, Server Summary, Roles Summary, Features Summary and Resources and Support. Expand Server Summary.

3. Expand Security Information and on the right you should see a box that says “Configure IE ESC”. Click on that.

4. Select Off for both Administrators and Users and click OK.

Another easier way to directly access the Internet Explorer Enhanced Security Configuration window is to type the full link below in the run box.

“C:\Windows\system32\rundll32.exe” C:\Windows\system32\iesetup.dll,IEShowHardeningDialog
