After 6 years of working with Windows Server 2003 I finally made this script to disabe the restricted IE mode. Microsoft already fixed this feature for Windows Server 2008 and it can be easly switched off in Server Manager. For Windows Server 2003 you still need to open appwiz.cpl and run the steps.

The screenshot below made me creating this script:

disable Internet Explorer Enhanced Security Windows Server 2003

Microsoft Internet Explorer’s Enhanced Security Configuration is currently enabled on your server. This enhanced level of security reduces the rish of attach from Web-based content that is not secure.

This message make sense but not when I need to update latest firmware, drivers or work on a CA as shown in my example.

Create new file named disable “IE-Security.txt”  and paste text below.

[Components]
IEHardenUser=Off
IEHardenAdmin=Off

Save the file and run SYSOCMGR.EXE /i:%windir%\inf\sysoc.inf /u:c:\IE-Security.txt

This made my server now less secure but my life easier to get this done.
