Here is PowerShell command to list all authorized DHCP servers from Active Directory. Replace the DOMAIN and COM with your domain name in the command below.
Get-ADObject -SearchBase “cn=configuration,dc=DOMAIN,dc=COM” -Filter { ObjectClass -eq ‘dhcpclass’ } | Select-Object Name | Format-Table –Wrap
I used format-table with wrap option to display full DHCP server name if it is long name.
If you browser the same location (in SearchBase in Get-ADObject cmdlet) in AD Sites and Services (with services option enabled), you will see the DHCP servers. This command list those DHCP servers, that’s all.
