Machine that are deployed via Microsoft Deployment Toolkit (MDT) are provided with a computer name that’s provided during installation. By default this is a generated computer name similar to “MININT-79S84T2”.
Since the GUI of MDT is quite slow – and won’t show an hourglass – I noticed people tend to click [Next] twice on the previous screen. As a result they automatically accept the generated computer name instead of providing their own. It’s more friendly to block the [Next] button on the Computer Details screen so users are force to provide a proper computer name.
