Last month I had couple of clients that needed to restore accidentally deleted user and computer account. Though there is a command line version of tombstone reanimation tool called adrestore , the clients were not CLI savvies and having a GUI version of this functionality could really help them out. Some time ago I wrote a GUI version just for the case in VB.NET, but as it turned out it was quite buggy (well, it was one of my first .NET GUI apps), so I set down and rewrote the application from scratch...
