Removing AD DC Metadata Script

This is a very useful script to automatically remove the metadata from Active Directory upon the loss of a domain controller that cannot be recovered or you will not be replacing and cannot gracefully demote. Just copy the text below and create your own script.

**I didn't write this script but since it is very useful I wanted to post it as another place to find it**
