How to Configure Security Settings

  • Article

You will need to configure the security settings for Microsoft 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
  • Add the Component Services Snap-in
  • Adjust Security Settings for WIA Device Manager
  • Adjust Security Settings for WIA Logger
  • Reboot
