I encourage you to go to this page https://community.landesk.com/support/docs/DOC-23470 and keep it bookmarked for all of your future provisioning needs.
Now, I also suggest that you create a template using the "BASIC LANDesk Support created" unattend script for the appropriate OS version you are using. Run that very basic build and insure that you do not have a problem somewhere in either your process or your infrastructure. This is a must, because ANY little deviation from the "golde4n path" of OS Provisioning will result in failure. So it is very helpful to use the process that Roy Meyer outlines here https://community.landesk.com/support/docs/DOC-27038 and just make a basic image using his scripts. Once that works you can add pieces to see if there is another problem elsewhere, but it will be easier to make the call on where the offender is at that point.
