How to Configure Security Settings

You will need to configure the security settings for Windows Image Acquisition (WIA) before you can successfully create a DeviceManager object on an Active Server Pages (ASP) page. This configuration is necessary because the script in an ASP page runs in the context of the IUSR_MACHINENAME or IWAM_MACHINENAME account (where MACHINENAME is the uppercase computer name).

This topic outlines the necessary steps to configure WIA security settings.

Run the Microsoft Management Console

Click Run on the Start menu, type mmc and click OK.
