Since changing which port the mini switch is that I use for imaging is plugged into on the core network switch, I am no longer able to send images.

I can schedule the image, and the machien pxe boots, goes through as far as checking disks etc, then hangs at the blue "please wait" screen.

We're currently mid-rollout of windows 7, so as you'll imagine this is critical.

Can anyoen suggest what could be causing this?
