You should start your Active Directory design with the namespace.
However, you will not be able to complete the logical namespace
design until you have the physical design sketched out.
It's very much a chicken-and-egg situation. You
should plan to go through and complete a rough draft of the namespace
design, then make a rough draft of the physical design, then consider
modifications to both.
Next you can consider the Group Policy Object (GPO) design. Group
Policy Objects control such things as user-environment lockdown,
forced registry changes, application availability, and so on, to sets
of machines or users. Because these relate to sites, domains,
Organizational Units, users, computers, and groups in your Active
Directory, it makes sense in my experience to incorporate these
changes into a namespace and site design that already exist.
You can then take a look at security and at tailoring Active
Directory to your own requirements by modifications to the Schema.
Finally, this section takes a brief look at the present and the
future of integrating and interoperating Active Directory with other
directories and operating systems and of migrating to Active
Directory.
