A Journey Through Discovery

    I would have to say that this topic is probably one of the biggest pet peeves of mine in the Information Technology field. Why do Systems Administrators not use Security Groups correctly (mind you, Microsoft administrators usually)? Why do I go to a site and most often find that permissions are given directly to a…

  • Change the Canonical Name (CN) of an Active Directory User

I may miss things along the way and my setup most likely differs compared to yours.

I hope you find this site has some value to you.
