If you try to create an OU and give it the same name as a child domain that already exists, you’ll get the error message


Active Directory<br><br>
Windows cannot create the object because: An attempt was made to add an object to the directory with a name that was already in use.<br>
Name-related properties on this object might now be out of sync.<br>
Contact your network administrator.


If you try to create a child domain and give it the same name as an OU that already exists, you’ll get the error message

Microsoft is aware of these restrictions, and no workarounds exist.
