Deploying Multiple Machines with Same Image

Having issues when I am deploying same image to multiple same type computers at the same time. Only 1 or 2 at the most succeed, the rest fail saying 'failed to deploy image' followed by 'image corrupted'. Does anyone have any ideas why this may be happening. I know the image is good it just seems to not want to deploy to multiple machines at the same time with no rhyme or reason.

Thanks in advance,

Matthew
