I am a consultant / admin / tool writer who happens to have a “secret” identity as a Microsoft MVP for Windows Server Directory Services. By day I work for a large unnamed tech company and by night I sleep.

The posts reflect my own homegrown approach to problems I encountered and are entirely based on my own experiences – I will try to avoid theorising!
