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.

To track your progress in the following table, select the check box next to each step.
