By default, pressing the F12 key in Internet Explorer displays the developer tools bar at the bottom of the Internet Explorer window. If the user is an administrator who needs to access the Integrated Dell Remote Access Controller (iDRAC) to work with physical servers, this can be a problem as the BIOS on the servers is configured to use F12 to select boot options during power-up. In Internet Explorer, pressing F12 displays the Developer Tools bar instead of the server’s boot options.
This can be corrected on an individual PC basis by setting the following registry key for any user who needs access to the iDRAC:
This key should be created as a DWORD with the value of 1.

Note that these keys can be set on a per-user basis, configured in the default system image, or pushed out through Group Policy preferences, set by a script, etc. – whatever makes sense in your organization.
