I've run into that myself using Ghost 2003 with XP, one clone would be OK then another would not, I'm beginning to wonder if its the Ghost 2003 feature of marking the hardrive thats causing the problem, I've got a friend with Ghost 2002 and he never has a problem with his clones in XP, it just doesn't make any sense.
