Microsoft's official enterprise support blog for AD DS and more
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 Conflictshttp://technet.microsoft.com/en-us/library/testing-for-active-directory-schema-extension-conflicts(WS.10).aspx
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.
