how to change domain of computer in many computer in all of our company?

Question

I would like to change abc domain to def domain for all computers on my network.

How do I change them all on the network and backup?

My server is Windows Server 2003 and it is used as an Active Directory and domain controller.

(Also, what about software that can be used in Active Directory?)

Answer 1

Make sure you have a very good business case for doing this... if you have applications in your environment that depend on Active Directory, they will likely break. If you have Exchange 2003, it requires you to run a fix-up tool afterwards. You cannot do it if you have Exchange 2007 or 2010 in your environment. MOM/Operations Manager will need to be uninstalled before the domain rename and reinstalled afterwards. SQL connection strings will need to be updated manually (those are just off the top of my head). You will need to test everything in a lab so that you find out what will/will not work in your own environment.

If, after all that, you decide to proceed... here is how to do it:

Another option would be to create a new domain and migrate over the users and computers using ADMT (guide here: http://technet.microsoft.com/en-us/library/cc974332(WS.10).aspx)

Answer 2

do you mean rename an Active Directory domain?

I think you need to elaborate a little more. Although my powers of mental telepathy have improved since I first started answering questions on serverfault, they're not that good.

Answer 3

Or us the Active Directory Migration Tool if you prefer the GUI.

Answer 4

Use good network management software

Answer 5

you can script this using netdom.exe

NETDOM /Domain:def /user:adminuser /password:apassword MEMBER
