In this document, we will discuss the proper steps for renaming a Microsoft Windows Server-based domain controller 2008, I know it's something unusual, but we will have to take it into account for when it is time, since there are several reasons that come to mind ;). We can run this wizard through GUI or via command line, I will choose this last option since it will be valid for Windows Server servers 2008 Core. We will take into account that if the server has the role of Certificate Authority or Certificate Authority (AC) We will not be able to change the name.

We open a DOS console, We rely on the NETDOM.EXE command to perform the task, by the:

netdom computername NOMBRE_VIEJO_DC_COMPLETO /add:NOMBRE_NUEVO_DC_COMPLETO

Ok, With this, What we achieve is to create the name that we want to give as an alternative name to this server. Modifying Service Principal Name Attributes (SPN – Service Principal Name) in your team account in the Active Directory. After the command is completed, we must allow enough time for this change to be replicated to the rest of the domain controllers and DNS servers (in the logs), once this time has passed, We will be able to continue, otherwise, Some client computers may have problems.

Once the DNS records are correct and the updates about the computer account are also correct,, we can now set the name as primary by the command:

netdom computername NOMBRE_VIEJO_DC_COMPLETO /makeprimary:NOMBRE_NUEVO_DC_COMPLETO

List, We must reset for the changes to take effect,

Once restarted and seen that we have no problem, We can now remove the old domain controller name from the computer alternative names with:

netdom computername NOMBRE_NUEVO_DC_COMPLETO /remove:NOMBRE_VIEJO_DC_COMPLETO

List!!
