One of the first things I usually do when I install a new Windows Server in a test environment, is to turn off Internet Explorer Enhanced Security Configuration (IE ESC). I am talking about this little prompts that get on your nerves whenever you open a website in Internet Explorer on a Windows Server. I described how to disable Internet Explorer Enhanced Security in Windows Server 2003 a while back. Since it is one of the popular articles here on 4syosps and because the procedure is different on Windows Server 2008, I decided to post a follow-up to save you from this constant security prompts.
Usually, when you explain publicly how to turn off a security feature you will be confronted with protests in a moralizing undertone. Feel free to do this in a comment box below. I appreciate all kinds of objections. But let me explain first why I think that disabling Internet Explorer Enhanced Security is a good thing to do.
First of all, one shouldn’t open web pages on production server, anyway. So the best way to enhance security would be if one could uninstall IE entirely. Unfortunately, Microsoft doesn’t allow this, though IE ESC comes very close to a disabled Internet Explorer. Not because it really enhances security, but because it makes IE literally useless.
I just tried to access Microsoft’s homepage on a freshly installed Windows Server 2008. I had to click about ten times on this security prompt until the page was finally displayed. If you decide not to add the site to the trusted sites zone you might get away with just six clicks. If you click on any link the click orgy will usually start again. On other sites it might even be worse. I wonder who really uses IE on a server this way. And, I seriously doubt, that those who really do, know what they are actually adding to their trusted site zones all the time.
Anyway, my recommendation is to use Opera if you really have to access web pages on a productive server. This browser is more secure than IE or Firefox because the bad guys usually only focus on popular browsers.
In a test environment, where one doesn’t need this extra security, it makes sense to just disable Internet Explorer Enhanced Security. In Windows Server 2003, one has to uninstall the corresponding Windows Component. In Windows Server 2008, this doesn’t work anymore. You have to click on the root folder in Server Manager. Then you scroll down to the Security Information Section and click “Configure IE ESC”. You can turn off IE ESC for Administrators and/or for users. The latter probably only makes sense in a Terminal Server environment.
