Deploying AD(Active Directory) System was One of  My Dream

When i had installed systems like ISE, WLC, Firewall, ADC, most of them supported AD login.

And when i used computer in a company previous, some features like control panel were limited to access.

Now, I will install AD to manage my virtual machines.

First, it was so easy to install AD on a server, just click and click, but there are so many unknown words, forest, DNS delegation, and global catalog.

After just leave them as default, I changed hostname and dns pointing my domain controller of all server that i managed.

and then i can now connect to all my server with just one account managed by the domain controller.
