Use PowerShell to Remotely Rename Active Directory Computers

If you have your machines bound to an Active Directory domain, renaming computers is a snap thanks to the awesome power of PowerShell.

Renaming One Computer

Use the following command to remotely rename a computer:

Rename-Computer -ComputerName <OldName> -NewName <NewName> -DomainCredential <Domain\Username>

Some other useful switches:

-Force Forces the command to run without asking for user confirmation
-Restart Forces the computer to restart after the change is made
-PassThru Returns the results of the command, otherwise no output is generated

An example to force a computer named Machine1 to change to Machine2 and then immediately restart:


Keep in mind that if the -restart switch is not used then the changes will not take effect until after the client computer is restarted.

Renaming Multiple Computers

For the sake of this example, we’ll just be using two computers but this technique can be particularly useful when needing to rename a large number of computers.

First create a comma separated values (.CSV) file in the format of: OldName, NewName

This can be done with a simple text editor like Notepad, just save as a .CSV file extension.  I’ll specify a computer called Machine1 be renamed to Machine2 and another named Machine3 be renamed to Machine4 saved in a file called Comps.CSV:


Next I’ll use two PowerShell commands.  The first is to import my .CSV file into a variable I’ll call $Comps:

$Comps = Import-Csv C:\Users\Q\Desktop\Comps.csv -Header OldName, NewName

The second command loops through the .CSV, renaming each computer and forcing them to restart:

Foreach ( $Server in $Comps ) {Rename-Computer -ComputerName $Server.OldName -NewName $Server.NewName -DomainCredential AD\Qname -Force -Restart}
