Recently, I have a requirement to get list of operating system version of domain controllers and export to csv name and OS version of domain controllers and use it for OS upgrade task.
PowerShell Get-AdDomainController active directory gets domain controller information, it has name and operating system version information.
In this article, I will explain how to get name and operating system version of domain controllers and export it to csv file in PowerShell.
Get List of Domain Controller OS Version
Use Get-AdDomainController active directory cmdlet to get list of domain controller name and OS version with using below command
Get-ADDomainController -Filter * | Select-Object Name, OperatingSystem
In the above PowerShell command, Get-AdDomainController gets all domain controller using Filter and wild card character and pass domain controller objects to second command.
Second command uses Select-Object to select Name and Operating System version of domain controllers.
Output of above command to find OS version of domain controller as below
