Install DNS and Active Directory services

Before I will install all the other member server I have to set up a DNS Server with Active Directory.
New in Windows Server 2008 is the role based management.
After installing the "naked" server, you have to add roles to the server, e. g. DNS or Active Directory in our case.

This you can do at Start --> All Programs --> Administrative Tools --> Server Manager

On the left side you have to click on "Roles" --> "Add Role" and choose Active Directory.

After adding the roles, you have to run dcpromo.exe

After the reboot the server is configured and you can start to add other servers or clients to the domain and beginning to create group policies etc.
