Hi Thanks for such a nice article. As said by all the article is really very effective and usefulness. This article has stated how to step up steeply the active directory. Well apart from this i would love to read how to configure an audit policy also for the same. During today at active directory the most occurring problem is for auditing also. If this is stated in a proper manner then most probably it would be a great help to all. At present third party tools are only the best source for this.
And thanks again for this wonderful article.
