Les mandatory profils n'ont rien à voir et ne vont pas t'aider.
Les profils obligatoirs (ou mandatory) sont des profiles pour lesquels tous les changements effectués en cours de session ne seront pas sauvergardés. Cela permet qu'à chaque logon, le profil soit exactement le même que la fois précédente. Pour votre info, pour créer un mandatory profile, il suffit de renommer ntuser.dat en ntuser.man et le tour est joué.
Pour ton histoire, lorqu'un nouvel utilisateur se logge sur Windows, l'OS prend une copie du profile default et le renomme avec le nom de l'utilisateur.
J'ai touvé l'article suivant sur le site de Microsoft qui décrit comment faire :

SUMMARY
This article describes how to create a custom default user profile in Windows 2000. A custom default user profile is helpful if several people use the same computer but each user wants a separate profile along with access to shared resources. When multiple users log on locally to the same computer, Windows 2000 uses the built-in default user profile as a template to assign a profile to each new user. You can replace this built-in profile with a custom default user profile so that each new user receives a custom version of the profile.  
 
Because this change is permanent, it is a good idea to make a backup copy of the default user profile, in case you ever want to use it again. The default user profile is in the Default User folder under Documents and Settings.
 
Create a Custom Default User Profile
Log on to the computer as the administrator, and then create a local user account.
Log off as the administrator, and then log on to the computer through the local user account that you just created.
 
Note that permissions issues will result if the custom user profile is created when you log on as an administrator.
Customize the profile appropriately. For example, install printers and map necessary drives.
Log off as the local user, and then log back on as the administrator.
Because several of the files in the profile are hidden and must be copied into the new custom default user profile, turn on the Show hidden files and folders option:
Double-click My Computer, click Tools, and then click Folder Options.
On the View tab, under Advanced settings, click Show hidden files and folders, and then click OK.
Replace the current default user profile with the customized default user profile:
Click Start, point to Settings, and then click Control Panel.
Double-click System.
On the User Profiles tab, click the user profile that you just created, and then click Copy To.
In the Copy To dialog box, under Copy profile to, click Browse, click the \Documents and Settings\Default User folder, and then click OK.
Under Permitted to use, click Change, click Everyone, and then click OK.
Windows 2000 will now assign the custom default user profile to any new user who logs on to the computer.
