Not using MDT yet. i can't get sysprep /unattend:unattend.xml to prompt for computer name

<settings pass="specialize">

        </component>
    </settings>

This is in an unattend.xml file that is on a virtual floppy, after i run:  sysprep.exe /quiet /generalize /oobe /reboot /unattend:A:\unattend.xml

After the system reboots, i don't get a prompt for computer name.  Everything i read says to remove <computername></computername> .  But that does not work.  I'm installing windows 2008 R2 w/ SP1.

Thanks,

Nick
