Windows XP Pro

Are you talking for the initial install of XP or once the OS is already loaded?
If you are talking about forcing a common desktop configuration on all users, the answer is: Use Group Policy Objects (GPOs) (hopefully you are using Win2K as the network OS). Through the use of GPOs, you can affect almost every aspect of a users interface with his/her computer (i.e. what the desktop looks like, what customizations a user is allowed, whether they can see the control panel, whether they have the right to add printers, whether or not they can see My Network (or network neighborhood), what they see in the Start menu, and on and on).

Once you have one PC configured, you can use the file and settings transfer wizzard to import the settings to each of the computers.

Is this for all users to access the same programs, desktop and start menu, my documents setup by the admin in XP Professional
