Disjoin Rejoin Windows Server

Question

I have a bunch of Windows 2008 R2 and Windows 2012 R2 that I need to remove from their current domain membership and add them to a new domain. Are there any tools or automated process I use to accomplish this task? Thanks a bunch.

Answer 1

You can use PowerShell

Add-Computer -ComputerName Server01, Server02, localhost -DomainName Domain02 -LocalCredential Domain01\User01 -UnjoinDomainCredential Domain01\Admin01 -Credential Domain02\Admin01 -Restart

@Anonymous Thanks. I tried similar commands. Are there any specific services or software that need to be enabled/ installed on the target servers?

Answer 3

If that doesn't work for you then ADMT may work.

@Anonymous Is there a way I can combine the disjoin from the domain on multiple computers, then pause the script for a few minutes then run the next block of line code to add the computers to another domain? I have the samples below, but I am stuck on how I can pass the local administrator user and password once the computer is standalone in a workgroup.

Disjoin from domain:
Remove-ADComputer -computername (get-content C:\Temp\servers.txt) -restart

Join to domain:
add-computer -computername (get-content C:\Temp\servers.txt) -domainname my.domain.com –credential mydomain\johsmith -restart –force

I looked at ADMT tool but I was hoping I can accomplish this via PS scripting for easier execution. Reading the ADMT notes it makes reference to installing a ADMT Agent to all target computers, which is more than I was hoping to deploy. I appreciate the info on the ADMT; but if someone can suggest a PS scripting way. If it helps all target servers in the domain I want to unjoin them from are running OS versions of Windows 2008 R2 and Windows 2012 R2 and a few Windows 2016.
