How to configure active directory in windows 7?

I just installed Remote Server Administrative Tools (RSAT) on windows 7, and tued features on as mentioned in the installation guide. Now the Administrative Tools have been installed and successfully listed in the All Programs list of start menu.

I want to set up a local network. I want to create users/passwords, and give them access to shared drives with permissions, etc.

My questions is:

How do I configure the Active Directory in windows 7 for the first time?
