ImageX and WIMs (can I strip hostname)

[ericargyle]

I'm currently using ImageX to blast out system-specific WIM images to add to my WDS server. This works beautifully, however, my employees need to manually change the hostname and rejoin to the domain before having a working system. Is there a simple way for me to strip out the hostname during or prior to the ImageX blast. Is there a sysprep switch I can run in PE that will ONLY remove the hostname and prompt for a hostname after deployment of each new system. Thanks so much for your help.
