If you are using an image, you would need to create the image every time you wanted to deploy it to have the latest dat files. I would not recommend deploying the Agent with your image. You will have the same Agent GUID each time you used the image. Push the Agent out to the new machine using ePO. Believe me it will keep you from having issues later. This is what my PC Support config center did, until I talked them into, not deploying the agent with the image. Once you have installed the agent, send a wakeup call, to update the dats.
