Branch Office Domain-Design

[Ziek]

I heard that for companies that consist of one main HeadQuarters location
along with several branch locations, that often an 2-Domain approach is
taken : One domain for HeadQuarters, and one domain for the Branches.

Can somebody explain why having only ONE-domain, which could handle both
Headquarters + Branches, is not good enough? If you can be smart about
domain controller placement and almost treat each branch as a separate site,
why not just have one domain?

The scenario that you speak of would only make sense under a few, small
instances --foreign country laws, enormous braches (big multinational
corporations), etc.

In most circumstances you would use one domain and simply use sites to
define the branches and possibly OUs as well.

MS recommend as flat a structure as possible with as few domains as
possible.
