How to apply administrative templates silently

[MOONLIGHT SONATA]

I've a few customized administrative templates. For example,

services.adm => Administrative template for controlling Windows services startup types

startmenu.adm => Enable changing the start menu locations in Windows 2000 and possibly XP.

inetsett.adm => Internet Settings Policy Template File

Now, i want to implement these templates during unattended deployment silently. During, post setup phase, which is the command-line that could help me add these templates so that before any user starts using the machine, policies are already set right-through the unattended installation.

Thanks in advance.
