In our system the all the computers have image. as it is
an eduactional centre we have to restore image on weekly
bases. All the Pcs are joined to the domain . After
restoring the image when we log on the doamin it gives an
error saying that computer's account is missing in the
domain. and even sometimes when image is not restored
after some time we get the same error it seems that
computer accounts are expiring in domain . Please note
that we create an image on one computer and distribute it
on all the other computers.and the after restoring the
image on other pcs we rename and then disjoin and rejoin
to the domain still after some time we get the same error
of computer account missing in the domain although it
exist in active directory. The soloution that i'm using is
running the sysprep utility every time the image is
restored. Kindly provide me a soloution for this.I know I
wrote a long story but i hate to run sysprep every week on
150 pcs every week so plz help me Thanking in advance.
