Как посмотреть fqdn в windows

Как узнать FQDN компьютера

Иногда в скрипте PowerShell требуется определить FQDN компьютера, на котором этот скрипт запущен. Сделать это можно разными способами, например можно воспользоваться переменными окружения.

Так переменная $env:COMPUTERNAME хранит имя компьютера, а $env:USERDOMAIN — имя домена, в котором этот компьютер находится. Объединив обе переменные мы получим полное доменное имя компьютера:

$name = ″$env:COMPUTERNAME.$env:USERDOMAIN″

Также для получения FQDN можно использовать WMI, а точнее класс Win32_ComputerSystem, в котором хранится информация о системе. Для начала получим все свойства этого класса и поместим их в переменную:

$systeminfo = Get-WmiObject -Class Win32_ComputerSystem

А затем возьмем нужные нам свойства, объединим их и получим имя компьютера:

$name = ″{0}.{1}″ -f $systeminfo.DNSHostName, $systeminfo.Domain

И третий способ — это воспользоваться статическими методами GetHostByName или GetHostEntry класса System.Net.Dns. Так получить FQDN текущего хоста можно всего одной командой:

$name = [System.Net.Dns]::GetHostByName(″localhost″)

What is FQDN and PQDN in DNS?

A Fully Qualified Domain Name (FQDN) is a domain name that specifies the exact location of a host within the tree hierarchy of the Domain Name System (DNS).If the name isn’t fully specified and is missing certain components, it is called a partially qualified domain name, or PQDN.

What is difference between FQDN and DNS?

Most of the answers here aren’t quite right. The settings mentioned are for the configured domain, however that may not be the domain the computer is actually on. The domain changes depending on what the computer is connected to — one WiFi connection may go to one domain, and a different one to another. Then connecting on VPN will put you in yet another domain. In all the cases the registry setting shown, and the USERDOMAIN and USERDNSDOMAIN environment variable values will remain unchanged.

To get the actual domain on which the computer is connected — use the «ipconfig» command line command, and see the «Connection-specific DNS Suffix» value. Note, for instance that if you disconnect or disable your connection, that will go away, indicating (correctly) that you are no longer in any domain.

A computer can, in fact, be connected on multiple domains, even, by connecting multiple ethernet ports, wifi ports, etc. to different places.

I want to retrieve the FQDN name of windows server via powershell script. I have found 2 solution so far:

$server =  Invoke-Command -ScriptBlock {hostname}

Above line will print just the short name of the server

$sysinfo = Get-WmiObject -Class Win32_ComputerSystem
$server = “{0}.{1}” -f $sysinfo.Name, $sysinfo.Domain

Above two line will get me the FQDN but this looks really nasty code to retrieve just the hostname

So, My question is, is there an easier way to get the FQDN in powershell. I am a bash/perl coder and recently picked up powershell.. so finding it difficult.

Thanks.

To get FQDN of local computer:

[System.Net.Dns]::GetHostByName($env:computerName)

[System.Net.Dns]::GetHostByName($env:computerName).HostName

To get FQDN of Remote computer:

[System.Net.Dns]::GetHostByName('mytestpc1')

For better formatted value use:

[System.Net.Dns]::GetHostByName('mytestpc1').HostName

For remote machines make sure host is reachable.

How about: "$env:computername.$env:userdnsdomain"

This actually only works if the user is logged into a domain (i.e. no local accounts), logged into the same domain as the server, and doesn’t work with disjointed name space AD configurations.

Use this as referenced in another answer:

$myFQDN=(Get-WmiObject win32_computersystem).DNSHostName+"."+(Get-WmiObject win32_computersystem).Domain ; Write-Host $myFQDN

[System.Net.Dns]::GetHostByName((hostname)).HostName

$env:computerName returns NetBIOS name of the host, so that both previous examples return
netbioshostname.domainsuffix (not FQDN!)
instead of
dnshostname.domainsuffix (FQDN)

for example, host has
FQDN
aa-w2k12sv-storage.something.com
and NetBIOS name
aa-w2k12sv-stor (an easy case, I usually change NetBIOS name)

the hostname utility returns dnshostname, i.e., the first part of FQDN and code

[System.Net.Dns]::GetHostByName((hostname)).HostName

returns the right FQDN

Comment: never use the same NetBIOS and DNS names of AD domains and hosts. If your or 3rd party application writes to the log: «cannot connect to hostname.domainsuffix», what name it tries to resolve? If you see in the log «cannot connect to netbiosname.domainsuffix», no doubt, a lazy programmer added domain suffix to the NetBIOS name and you are sure, this is a bug, and can open a ticket to force them to fix the issue…

to get the fqdn corresponding to the first IpAddress, it took this command:

PS C:\Windows\system32> [System.Net.Dns]::GetHostByAddress([System.Net.Dns]::GetHostByName($env:computerName).AddressList[0]).HostName
WIN-1234567890.fritz.box

where [System.Net.Dns]::GetHostByName($env:computerName).AddressList[0] represents the first IpAddress-Object and [System.Net.Dns]::GetHostByAddress gets the dns-object out of it.

If I took the winning solution on my standalone Windows, I got only:

PS C:\Windows\system32> (Get-WmiObject win32_computersystem).DNSHostName+"."+(Get-WmiObject win32_computersystem).Domain
WIN-1234567890.WORKGROUP

that’s not what I wanted.

Here is a way to determine the FQDN of a server based on the «Name» and «DistinguishedName». Works for multiple domains:

$server = Get-ADComputer serverName -Server domainName -Properties * | select Name, DistinguishedName
$domain = $server.DistinguishedName -split ","
$domain = $domain | ? {$_ -like 'DC=*'}
$domain = $domain -join "."
$domain = $domain -replace "DC="
$FQDN = $server.Name + "." + $domain

If you have more than one network adapter and more than one adapter is active (f.e WLAN + VPN) you need a bit more complex check. You can use this one-liner:

[System.Net.DNS]::GetHostByAddress(([System.Net.DNS]::GetHostAddresses([System.Environment]::MachineName) | Where-Object { $_.AddressFamily -eq "InterNetwork" } | Select-Object IPAddressToString)[0].IPAddressToString).HostName.ToLower()

How about this

$FQDN=[System.Net.Dns]::GetHostByName($VM).Hostname.Split('.')
[int]$i = 1
[int]$x = 0
[string]$Domain = $null
do {
    $x = $i-$FQDN.Count
    $Domain = $Domain+$FQDN[$x]+"."
    $i = $i + 1
} until ( $i -eq $FQDN.Count )
$Domain = $Domain.TrimEnd(".")

#I "know":        "MyAppServer" .. I pass this on as an env var called myjumpbox .. this could also be $env:computername


$forname                 = $env:myjumpbox
$fqdn                    = [System.Net.Dns]::GetHostByName($forname).Hostname
$shortname               = $fqdn.split('.')[0]
$domainname              = $fqdn -split $fqdn.split('.')[0]+"."
$dnssuf                  = $domainname[1]  
" name parts are- alias: " + $forname + " actual hostname: " + $shortname + " suffix: " + $dnssuf

Using Resolve-DNSName command this way works for PowerShell 5.1 and 7.3 in my case.

(Resolve-DnsName -Name 'hostname').Name

Supporting Resource

Resolve-DNSName

Description

The Resolve-DnsName cmdlet performs a DNS query for the specified
name. This cmdlet is functionally similar to the nslookup tool which
allows users to query for names.
