Getting ready

Microsoft recommends raising the FFL from the Active Directory domain controller that holds the Domain Naming Master FSMO role.

To locate this domain controller, run the following command on any domain-joined device, member server, or domain controller:

netdom.exe query fsmo

Alternatively, use the following PowerShell commands on a domain-joined system that has the Active Directory module for Windows PowerShell installed:

Import-Module ActiveDirectory

Get-ADForest | Format-List DomainNamingMaster
