Running Windows Core Series, what's my name and how do I change it?
When running these commands or using them in scripts keep in mind that some may become deprecated in future versions of Windows. Best practice is to use the PowerShell commands when possible to future proof any script that use these commands. These commands were run on Windows Server 2012R2.
When running Windows Server 2012+ without a GUI note that the GUI can be reinstalled via PowerShell (Install-WindowsFeature) and a reboot.
From Windows Server core command prompt:
PS C:\>$dns=Get-DnsClient|select Hostname;$dns
C:\>WMIC COMPUTERSYSTEM LIST BRIEF
C:\>NETDOM COMPUTERNAME . /ENUMERATE
*Will show any alternate names added via NETDOM.
To change the local computer name (Non-Domain):
C:\>WMIC COMPUTERSYSTEM WHERE NAME="%COMPUTERNAME%" RENAME NAME="2012R2Core"
PS C:\>Rename-Computer -NewName 2012R2Core2 -ComputerName .
Change the computer name (Domain joined):
PS C:\>Rename-Computer -NewName 2012R2Core2 -ComputerName . -DomainCredential domain\user
