Disabling Internet Explorer Enhanced Security Configuration
Windows Server 2003 is shipped with security locked down by default. Part of this locking down is Internet Explorer Enhanced Security which is an extra layer of protection when surfing the internet using Internet Explorer.
You can uninstall the entire Configuration, or just for users, or just for Administrators.
The un-installer is set up like this:
Enhanced Security ->For Administrators ->For Users
If you have non-admin users connecting via Remote Desktop or Terminal Services, you may wish to leave the Users configuration installed. This tutorial will remove it for all users.
Click Start, then Control Panel, and then select Add/Remove Programs
Click Add/Remove Windows Components
A window will pop-up, click the check mark next to Internet Explorer Enhanced Security Configuration (to uncheck it). If you'd like to only disable it for Administrators or for Users only you can click "Details" and change this setting individually.
Press Next, it will take a couple of seconds to finish, and then it's all done!
For Windows 2008 it is a little different
First, open the Server Manager by going to Start > Server Manager
In the Server Manager browse to the Security Information section in the right hand pane and click 'Configure IE ESC'. IE ESC is located in the very lower right-hand corner of the window.
In the Internet Explorer Enhanced Security Configuration window decide for whom you want IE ESC enabled or disabled and click OK.
It can be enabled/disabled for Administrators only or for all users
