Help!!!!!

What i am using :

Ghost enterprise 8.0
working on a lan with 11 identical computers and one for administration purposes. altogether 12 pc's.

I have created an image using pxe and ghost cast. That worked fine. The problem lies here: when i try to restore (with the image that i have created) more than 2 computers at once it hangs (message at the bottom left corner of the screen 'Restoring... NTFS MFT Table') after a few seconds, and after a few minutes it only one will go through and restore but the rest will time out.

When i try to restore them one at a time, it works. = sending one image to one pc at any one time. (very time consuming)

Please help....
Its doing my head in!!!!

The LAN is not connected via a hub by any chance, is it?

The network is correctly configured. It allows me to send the image to many via the ghost console.

The problem is that when i use pxe and ghost to send an image to more than 1 computer then it hangs.

I forgot to mention but i do have SATA drives. Will that be a cause??????
