We have published a new topic and script about how to test an Active Directory schema extension for potential conflicts before you apply the extension. The topic is http://technet.microsoft.com/en-us/library/testing-for-active-directory-schema-extension-conflicts(WS.10).aspx. The script is for Windows PowerShell and posted at http://gallery.technet.microsoft.com/ScriptCenter/en-us/0672d181-ab2c-4c92-8466-d93a67412207. The goal for the topic and script is to give customers more confidence about applying schema extensions.

Any feedback about the topic and script is greatly appreciated.
