Repartition with an Unattend Script

Hello,
Does anyone know a way to allow my users to connect to my windows 2000 distribution share and install a new clean install of windows 2000 Professional the catch is that I want everyone’s current partitions to basically delete from the WIN 2000 setup and then repartition to use the whole entire drive space. This can easily be done when booting from the CD but will not work when my users run the unattend script over the network.

Thanks,
Mark
