[ActiveDir] Geographic Domain Setup

[Edwin]

Hello Everyone.   The company that I work for has been divided into two isolated parts.  As a result the corporate domain that is used will also need to be divided.  The employees of the old domain will remain in their place while others will be put into a new domain.  One domain will have nothing to do with the other.  I have been tasked with heading the creation of a new domain that will be used in different geographic locations;   Atlanta, Georgia Miami, Florida Orlando, Florida Houston, Texas Fremont, California Vancouver, Canada   I have built a domain before but this was for one office of less than 100 employees.  This domain is of a much larger scale and more complex.  I have read a few MSFT articles and have a little bit of information as to what I am getting myself into.  I was hoping that I would be able to get more information from the community in hopes of getting real life experience knowledge than a document that outlines best practices.   When I built the single site domain I had the below configuration that worked very well for me.  I think that I am going to create a similar if not exact root domain.  I think that I would am having more problems with considering the geographic issues that I will be facing.   2 Domain Controllers             Both DNS Servers             FSMO roles divided             Both Global Catalogs 1 File Server             Roaming Profiles             Centralized Storage for User Files 1 Anti-Virus Server 1 WSUS Server 1 Exchange Server   Thank you all for your replies, Edwin
