Path in the GPO console
Computer Configuration\Administrative Templates\System\Scripts Description
This policy setting allows user logon scripts to run when the logon cross-forest, DNS suffixes are not configured, and NetBIOS or WINS is disabled. This policy setting affects all user accounts interactively logging on to the computer. If you enable this policy setting, user logon scripts run if NetBIOS or WINS is disabled during cross-forest logons without the DNS suffixes being configured. If you disable or do not configure this policy setting, user account cross-forest, interactive logging cannot run logon scripts if NetBIOS or WINS is disabled, and the DNS suffixes are not configured.
