following is from ref.chm
I was getting also some different errors with FullUnattended switch, that's why I now using DefaultHide switch (it works like FullUnattended switch if you have all answers in winnt.sif)DefaultHide
Specifies that answers in the answer file are defaults. Unlike UnattendMode = ProvideDefault, Setup does not display the user interface to end users if you specify in the answer file all the answers relating to a particular Setup page. If you specify only subsets of the answers on a page, the page appears with the provided answers. The end user can modify any of the answers on the displayed page.
Use UnattendMode = DefaultHide in deployment scenarios where an administrator might want only end users to provide the administrator password on the computer. This behavior is the default if you do not specify unattended mode.
FullUnattended
Specifies a fully unattended GUI-mode Setup. If you do not specify a required Setup answer in the answer file, Setup generates an error.
During an attended Setup, improperly signed hardware drivers generate a warning dialog box. If UnattendMode = FullUnattended, then Setup does not install hardware drivers unless they are properly signed.
Use UnattendMode = FullUnattended in deployment scenarios where you require a complete unattended installation.
