Something I need to progess is my .Net related AD skills. I have done a considerable amount of ASP.NET but none of it really related to Active Directory. Recently I have had a couple of requests to look at health checks around the directory and how they can be globally achieved.  Looking at the tools available none of them do everything you want and some of them cost a considerable amount of cash.  Perhaps writing something yourself is the only way to go ?

Anyone got any hints or tips on what they are doing?
