Learn about Windows PowerShell
Summary: Use Windows PowerShell to find the name and operating system version of all your domain controllers.
How can I use Windows PowerShell to find the name and operating system version of all my domain controllers?
Use the Get-ADDomainController cmdlet from the Active Directory module and a wild card filter to select all domain controllers. Then pipe the results to the Select-Object cmdlet and choose the Name and OperatingSystem properties.
Get-ADDomainController -Filter * | select name, operatingsystem
How can I pull this information from all child domains?
@Derrick The Get-ADDomainController cmdlet has a -DomainName parameter that permits you to specify the domain name. You could populate that value with your childdomains. The Get-ADDOmain cmdlet will return childdomains.
Get-ADDomainController -Filter * | select name, operatingsystem,HostName,site,IsGlobalCatalog,IsReadOnly | Export-Csv c:\dcinventory.csv
If you get the error
Get-ADDomainController : Unable to find a default server with Active Directory Web Services running
Then it's possible that the Domain environment is pre Server 2008 R2 judging by this post
But you can't be sure until you're able to query the OS version :)
I've been using this cmdlet in a script for over a year now, but since last week it's stopped working (possibly due to Windows Updates?). When I run Get-ADDomainController -Filter * now, I get the error message; "Directory Object not found". Is anyone
else seeing this? (DCs are Windows 2012 R2 by the way).
Hi TiDu, I experienced the same, Get-ADDomainController -Filter * is no longer working since a few days on 2012 R2 DCs.
Great post from your hands again. I loved the complete article.
By the way nice writing style you have. I never felt like boring while reading this article.
I will come back & read all your posts soon. Regards, Lucy.
