In order to move computer account to a different domain, we recommend to use the netdom command-line utility.
Netdom has many capabilities like :create one-way and two-way trusts between domains,add, join, and remove computers to or from the domains.
and reset secure connections between a workstation and a computer.
The netdom utility is part of the suptools.msi, which can be found in the Windows 2008 Server CD.
for example:
In oreder to join the LVT019 computer to the domain in the planning OU,
we’ll use the following syntax:
Netdom join / LVT019 /ou:ou=Design, dc=Pokerface, dc=com
