Unable to deploy more than one unknown machines

Hi guys,

I already configured ghost solution suite, I can take images from pxe, deploy images to one machine. So I decided to deploy to several machines but for some reason for example if I run 5 machines Im getting this error "Restarting DHCP clilent service:  retry 1..." in 4 computers and only one runs after this one completes if I connect a new one same error "Restarting DHCP clilent service:  retry 1..." so I have to reboot the ghost server but still only one runs

The ghost server is a windows 2012 and is a virtual machine, the DCHP server is other virtual machine and the computers I want to deploy to are physical.

What am I missing?
