I needed a way to let our technicians kick off a lite touch deployment and then know when it was complete in case they needed to return to finish any final steps in the re-image process. I added a custom pane to the deployment wizard to prompt the tech whether they wanted to be notified and by what method. I then used a web service to send the e-mail. I created a three part post to explain how I implemented this in my environment. It has been in place for over a year and is working great.
Part 1 discusses building the web service to send the e-mail notification.
Part 2 covers the scripts and files required for the task sequence and lite touch.
Part 3 lists the steps required to add the custom pane to the deployment wizard to pull it all together.
