We used the same method there with ghost software principally.
We have to readd machines also to Win Domains because of machine
passwords.
By default machine password are changed every week, so an image older
then a week fails it's autenthication because of wrong password.
Password are changed by the client and I do not know any way to avoid
it.
A way to not have the machine rejoin a sambaPDC server may be to save
the smbpasswd entry when you make the machine image and restore this
entry when you install back that image, this is untested anyway, but.
