13 janvier 2017 Nicolas PowerShell 0

This blog post explains how to get the Domain and Forest level of your Active Directory using Windows PowerShell.

There are 2 cmdlets:

Get-ADDomain
Get-ADForest

You can filter the results with Name and Domain/Forest Mode parameters:

PS C:\Users\Administrator> Get-ADDomain | fl Name,DomainMode


Name       : get-cmd
DomainMode : Windows2016Domain



PS C:\Users\Administrator> Get-ADForest | fl Name,ForestMode


Name       : get-cmd.Local
ForestMode : Windows2016Forest

PS C:\Users\Administrator> Get-ADDomain | fl Name,DomainMode

Name : get-cmd

DomainMode : Windows2016Domain

PS C:\Users\Administrator> Get-ADForest | fl Name,ForestMode

Name : get-cmd.Local

ForestMode : Windows2016Forest
