Question about NT AUTHORITY\INTERACTIVE

[holex]

Hi,

I am trying to build an unattended XP installation image.

For some reasons, the NT AUTHORITY\INTERACTIVE need to be added into administrators group, I had tried to include CPAU with command (cpau -u administrator -p 123 -ex "net localgroup administrators """NT AUTHORITY\INTERACTIVE""" /add) in cmdlines.txt,SetupParams,GUIRunOnce and RunOnceEX, but none of those could make that happen.

Above command is correct and could be processed successfully if I log on to XP with any account

What did I missed? can't find answer on Google.... hope someone here can kindly help~~~
