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).

The second variable is "%USERDNSDOMAIN%". – Benoit Oct 12 '09 at 13:36
%USERDNSDOMAIN% doesn't appear to be a variable on this system. Unless I'm doing something wrong: H:\>echo %COMPUTERNAME%.%USERDNSDOMAIN% [correctname].%USERDNSDOMAIN% – Grundlefleck Oct 12 '09 at 14:38
Ach, forgot that pasting that would be horrible in the comments. – Grundlefleck Oct 12 '09 at 14:39

You can use **WMIC** to retrieve domain name: `wmic computersystem get domain` – Noam Manos Apr 15 '15 at 07:14
This works only if the user is in the same domain like the computer. I suggest NOT to use %USERDNSDOMAIN% for the FQDN of the computer. – David Gausmann Mar 09 '21 at 11:59

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.

The two different ways give different results. ipconfig gives what I was expecting, but in the 'Computer Name' tab, the domain is different. It looks like a Workgroup name rather than a domain suffix. Is this a Windows specific thing where they are somehow equivalent? – Grundlefleck Oct 12 '09 at 13:00
In the "Computer name" tab, you should look at the "Full computer name" value; the "domain" value is the Windows domain (or workgroup) the computer is member of. – Massimo Oct 12 '09 at 13:23
Ah right. Well there must be something wrong with the install on this machine, as it's only showing the hostname (with a dot at the end). Probably wouldn't have had to ask the question if it had been showing it as expected :-D. +1 – Grundlefleck Oct 12 '09 at 13:28
Have you tried clicking on "Change" and then "More"? – Massimo Oct 12 '09 at 13:42
No, unfortunately I am unable to as I don't have administrator credentials on these specific machines. The ipconfig command worked though, so it's all good :) – Grundlefleck Oct 12 '09 at 16:19

Just remember some systems are localized so looking for the proper line by nr may be better in some cases (it's line 5 afaik). – RnR Jul 20 '17 at 11:10

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.

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%

Use four leading spaces to format your answer as 'code'. The ubiquitous 'help' link is actually helpful. – Jeter-work May 11 '17 at 17:52

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%

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