Rename a Server Core Install or Hyper-V Host Computer

I recently needed to rename a Hyper-V server (which is essentially a server core install of Windows Server 2008 R2). It took so doing, but I found the command.
[code]Netdom renamecomputer oldname /newname:newname /userd:someuser /passwordd:*[/code]
Replace the computer names with valid ones and a domain admin user, and the command will prompt for your password. That’s it, reboot and you’re set!
