How to Configure DUA to Poll a Web Server
5/10/2007
With the Device Update Agent (DUA) component, you can apply updates to a remotely deployed run-time image. The DUA service runs on the device, by polling a Web server for any updates.
QFEs for Windows XP Embedded cannot be directly applied to a deployed run-time image with DUA. Instead, the files that constitute the QFE must first be extracted. Then, you can author a script that copies the files to the device.
You must build a run-time image with the Device Update Agent component added to it before it can be updated.
