Hi folks, Ned here for a quickie. Back in April I posted a short mail sack piece about Schema updating best practices. Something I couldn't talk about that the time is now public:

Testing for Active Directory Schema Extension Conflicts

This article walks through using some simple techniques and a script to validate that an application's schema update is not going to cause issues. Nearly all AD Schema issues are caused by incorrect changes made by third parties - this article will help you prevent those issues.
