One of the more time-consuming tasks for a  XenApp administrator is to build new XenApp servers. This video shows how we can use Provisioning Server to

  1. Create an image based on a current installation
  2. Take the image and deliver to a whole slew of new XenApp servers

This process not only creates new XenApp servers, but it also adds them into the farm automatically.  Simply publish applications with a drag-and-drop and your done.  Because each XenApp server is coming from a single image, you can guarantee that each server is identical to each other, a very important XenApp best practice.
