The default configuration for Windows Server 2008 still has Internet Explorer Enhanced Security Configuration enabled. Considering most administrators probably disable this I wonder why it's still there ... nonetheless here is a script to disable Internet Explorer Enhanced Security Configuration (IEESC) from a script.
:: If required, backup the registry keys
:: This is always a good idea before making registry changes
REG EXPORT "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{A509B1A7-37EF-4b3f-8CFC-4F3A74704073}" "%TEMP%.HKEY_LOCAL_MACHINE.SOFTWARE.Microsoft.Active Setup.Installed Components.A509B1A7-37EF-4b3f-8CFC-4F3A74704073.reg"

:: If you like you modify the registry to remove the warning that shows on first IE run
:: This registry change will also set the default home page to about:blank
REG DELETE "HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main" /v "First Home Page" /f
REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main" /v "Default_Page_URL" /t REG_SZ /d "about:blank" /f
REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main" /v "Start Page" /t REG_SZ /d "about:blank" /f
Just another of those little Windows annoyances that can be removed easily if you like.
