I need a similar command to Linux' domainname on Windows without using any third-party application.

Is there such a command?

Try:

echo %USERDOMAIN%

or

echo %USERDNSDOMAIN%

If that still doesn't work, you can try using systeminfo:

systeminfo | findstr /B /C:”Domain”

Here is a tricky way that I did it using the net command and the find command in a batch file:

set command=net user "%USERNAME%" /domain | FIND /I "Full Name"



FOR /F "tokens=1 delims=" %%A in ('%command%') do SET fullNameText=%%A

set fullName=%fullNameText:Full Name=%

for /f "tokens=* delims= " %%a in ("%fullName%") do set fullName=%%a

The first line stores the command that we want to execute in a variable. It pulls the username from the environment variables and passes that into the net user command as well as the /domain parameter to tell it to pull from the current domain. Then it pipes the result from that, which is a bunch of data on the current user, to a find method which will pull out only the property that we want. The result of the find is in the format "Full Name John Doe". The second line will execute the command and put the result into the variable fullNameText. The third line will remove the "Full Name" part of the result and end up with " John Doe". The fourth line with the for loop will remove all of the leading spaces from the result and you end up with "John Doe" in the fullName variable.

The %USERDOMAIN% and the network computer domain can be different. The systeminfo command will get the right answer but it is SLOW! Here is a solution I've used:

@REM + find the computer domain name

 FOR /F "usebackq tokens=*" %%a IN (`ipconfig /all`) DO (

     @((ECHO %%a | findstr /i /c:"Primary Dns Suffix") && SET _str=%%a) > NUL 2>&1

 )

 FOR /F "tokens=2 delims=:" %%a IN ("%_str%") do SET _computerDomain=%%a

 SET _computerDomain=%_computerDomain: =%



 SET _fqdn=%COMPUTERNAME%.%_computerDomain%

@Mike: fine solution - but I had some problems with it in a multi-language enviroment.
I have German and English servers.

I changed your script to use wmic.exe:

@REM + Find the computer domain name

@echo off

FOR /F "usebackq tokens=*" %%a IN (`wmic.exe COMPUTERSYSTEM GET DOMAIN /Value`) DO (

      @((ECHO %%a | findstr /i /c:"Domain=") && SET _str=%%a) > NUL 2>&1

)

FOR /F "tokens=2 delims=^=" %%a IN ("%_str%") do SET _computerDomain=%%a

SET _computerDomain=%_computerDomain: =%

SET _fqdn=%COMPUTERNAME%.%_computerDomain%

echo %_fqdn%

Thx for your idea

One line is enought to get the domain using a local user:

FOR /F "usebackq tokens=2 delims==" %%a IN (wmic.exe COMPUTERSYSTEM
GET DOMAIN /Value ^|find /i "domain") DO set _computerDom=%%a

You can run below command on command prompt:

set user

It gives you a lot more information related to domain in addition to the name of domain as shown in below snapshot:

1. User DNS Domain


2. User Domain


3. User Domain Roaming Profile


4. User Name


5. User Profile

Important Note: Domain on which your computer is registered might not be same as the domain on which the logged-in user is registered. Please read about transitivity and direction in domain trust to know how a user registered in one domain can login to a computer on another domain.
