Equivalent of Linux command `hostname --fqdn` in Windows XP?

Question

Is there a way to find the fully qualified domain name of a Windows XP box?

Being unfamiliar with Windows I would describe what I'm looking for as the equivalent of the command hostname --fqdn available in Linux.

There is no such option to the hostname command in windows. However, this should do the trick:

echo %COMPUTERNAME%.%USERDNSDOMAIN%

Or you can grep (under Windows: find /I "string") for Host- and Domain from set or systeminfo or ipconfig -all name and glue it together elsewhere.

Edit: fixed Typo. Thanks Benoit

Update: The variable %USERDNSDOMAIN% is only available when logged on to a domain... The DNS suffix you get from a DHCP server is not put into a environment variable (as far as I could figure out).

You can find it in the system properties ("Computer name" tab).

With the command line, you can run IPCONFIG /ALL and have a look at the "Host name" and "Primary DNS suffix" fields.

ping -a localhost

Try this from the command prompt:

FOR /F "tokens=2" %i in ('systeminfo ^| find /i "Domain"') do echo %computername%.%i

remember to use double % for %i if using this in a batchfile. e.g. %%i

A reason you may want to do it this way is: if your users and computers are in different domains, the %USERDNSDOMAIN% will not be correct when applied to your computer. If you only have one domain and no child domains, then you can use the other solutions above if you like.

With PowerShell:

(gpv HKLM:\SYSTEM\CurrentControlSet\services\Tcpip\Parameters HostName, Domain) -join '.'

This will also work and does not have the delay of systeminfo:

for /f "tokens=2 delims=:" %i in ('ipconfig /all ^| findstr Search ') do SET domain=%i & SET newdomain=%domain: =% & echo %COMPUTERNAME%.%newdomain%

Another version:

echo.
echo Getting FQDN...
FOR /F "tokens=1-2" %%A in ('ping -a localhost -n 1') do (
    echo %%A | find /i "Pinging" >nul
    IF NOT ERRORLEVEL 1 SET "FQDN=%%B"
)
echo %FQDN%

use 'hostname' and combine with for /F "tokens=3" %%I in ('reg query "HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters" /v Domain') do set _MyDomain=%%I

An other way in PowerShell

Write-Host "$(Hostname).$((Get-NetIPConfiguration).NetProfile.Name)"

Or as a variable

$FQDN = $(Hostname).$((Get-NetIPConfiguration).NetProfile.Name)
$FQDN

Sample output

ServerName.ad.example.com

If you need to port Unix shell scripts to windows or just like to work on the CLI, have a look at GNUwin32. It provides the common tools like cut, grep, etc for Windows.

Here is a CMD script for this:

@ECHO OFF

FOR /f "tokens=2,* delims= " %%a in ('IPCONFIG ^/ALL ^| FINDSTR "Primary Dns"') do set tempsuffix=%%b
FOR /f "tokens=1,2 delims=:" %%a in ('echo %tempsuffix%') do set dnssuffix=%%b
SET FQDN=%COMPUTERNAME%.%DNSSUFFIX:~1%

ECHO Server FQDN: %FQDN%
