[windows] Change windows hostname from command line

Is it possible to change the hostname in Windows 2003 from the command line with out-of-the-box tools?

Here's another way of doing it with a WHS script:

Set objWMIService = GetObject("Winmgmts:root\cimv2")

For Each objComputer in _
    objWMIService.InstancesOf("Win32_ComputerSystem")

    objComputer.rename "NewComputerName", NULL, NULL 
Next

Source

cmd (command):

netdom renamecomputer %COMPUTERNAME% /Newname "NEW-NAME"

powershell (windows 2008/2012):

netdom renamecomputer "$env:COMPUTERNAME" /Newname "NEW-NAME"

after that, you need to reboot your computer.

Use below command to change computer hostname remotely , Require system reboot after change..

psexec.exe -h -e \\\IPADDRESS -u USERNAME -p PASSWORD netdom renamecomputer CurrentComputerName /newname:NewComputerName /force

If you are looking to do this from Windows 10 IoT, then there is a built in command you can use:

setcomputername [newname]

Unfortunately, this command does not exist in the full build of Windows 10.

I don't know of a command to do this, but you could do it in VBScript or something similar. Somthing like:

sNewName = "put new name here" 

Set oShell = CreateObject ("WSCript.shell" ) 

sCCS = "HKLM\SYSTEM\CurrentControlSet\" 
sTcpipParamsRegPath = sCCS & "Services\Tcpip\Parameters\" 
sCompNameRegPath = sCCS & "Control\ComputerName\" 

With oShell 
.RegDelete sTcpipParamsRegPath & "Hostname" 
.RegDelete sTcpipParamsRegPath & "NV Hostname" 

.RegWrite sCompNameRegPath & "ComputerName\ComputerName", sNewName 
.RegWrite sCompNameRegPath & "ActiveComputerName\ComputerName", sNewName 
.RegWrite sTcpipParamsRegPath & "Hostname", sNewName 
.RegWrite sTcpipParamsRegPath & "NV Hostname", sNewName 
End With ' oShell 

MsgBox "Computer name changed, please reboot your computer"

The previously mentioned wmic command is the way to go, as it is installed by default in recent versions of Windows.

Here is my small improvement to generalize it, by retrieving the current name from the environment:

wmic computersystem where name="%COMPUTERNAME%" 
     call rename name="NEW-NAME"

NOTE: The command must be given in one line, but I've broken it into two to make scrolling unnecessary. As @rbeede mentions you'll have to reboot to complete the update.

Why be easy when it can be complicated? Why use third-party applications like netdom.exe when correct interogations is the way? Try 2 interogations:

wmic computersystem where caption='%computername%' get caption, UserName, Domain /format:value

wmic computersystem where "caption like '%%%computername%%%'" get caption, UserName, Domain /format:value

or in a batch file use loop

for /f "tokens=2 delims==" %%i in ('wmic computersystem where "Caption like '%%%currentname%%%'" get UserName /format:value') do (echo. UserName- %%i)
