Hello,
I did a bad import of objects to the test AD lab and need to remove all objects. They located on many levels and sub OUs. Could you please help me with the script to get rid of them or maybe even the way to just remove entire AD quickly and start fresh.

Thanks

Try this and test on one OU: (To delete a container identified by its DistinguishedName including all child objects)
Remove-ADObject "OU=Finance,OU=London,DC=Mania,DC=COM" -Recursive

Yes on DC, start "Powershell with active directory" or use import
otherwise install the active directory module from google
import activedirectory
Remove-ADObject "OU=Finance,OU=London,DC=Mania,DC=COM" -Recursive

Alternatively, follow the steps to completely remove AD from the server.

On DC, run  "dcpromo"
tick "Delete the domain" Next...
tick "Delete all applications..."   Next...

Reboot

Again from server manager, click "Remove Roles"  and uncheck "Active Directory Domain Services" -> Next...
Reboot
