We are trying to ghost approximately 20 PCs using ghost across the same VLAN on a set of stacked 3750x switches. The problem is, during the ghost, several of the machines just drop out of the ghost session. The switches are 3750x-48t-l. Two switches are stacked together. All PCs and the ghost server are all on the same vlan. What could be causing the machines to dropout of the ghost session? Is there anything that could be run on the switch to make the ghost more efficient?
