Automation server can't create object error (Windows)

This error may be followed by a “Server Error 404 – File or directory not found” error and is caused by disabling “Run ActiveX controls and plug-ins” in Internet Settings (for the zone that applies).

This occurs because the JavaScript returned from the GS call tries to access the desktop app:

utility = new ActiveXObject("BlackBerry.DesktopNotifier.AtHoc");

.
