JSI Tip 7023. Windows XP Setup Manager creates a ProductID line, instead of a ProductKey line, in the [UserData] section of the unattended answer file?

The version of Setup Manager that is included with Windows Server 2003 has been revised to use the ProductKey keyword instead of the ProductID keyword.

If you create the unattended answer file using Windows XP, it still includes a ProductID=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX line.

To workaround this behavior, manually change ProductID= to ProductKey=.
