Where to find start.cmd template?

Hi people:
I’ve created about 80 samba user accounts, and realized that in every netlogon folder exists an initial start.cmd logon script.
But I can’t find where is the original or template file, or configuration, from which those scripts are created.
I need to change some values, and don’t want to change every single file.
Thank you very much.
Andrés.

New versions of the utilities keep all templates settings in one directory of the overlay.
Unfortunately ‘start.cmd’ hardcoded in utilities calculate-server ver 2.1.
