Hi All
Background Information
At present I have two offices one located in Canada the other in the Caribbean. Each office has its own domain and its own Active Directory structure. The offices are connected by a VPN. A two way trust relationship is configured between Barbados and Canada. Barbados office has a 768Kbps internet connection, Canada office (Main office) has a T1 internet connection. There are also some home offices located throughout Canada which also connect to the Canadian office using VPN connections. These home offices all have T1 internet connections. The Canadian office has 35 persons, Barbados 15 persons. Each office is presently running Exchange 2003 and Windows 2003.
Future Network
I am seeking to integrate the offices. I am thinking of implementing a simple network. Where I would have one domain, and two sites.
Do I need to have a domain controller in Barbados.
Do I still need to have two Exchange servers.
Should a Global Catalog server be located in each office.
Is there a way to implement a backup link to main office if internet connection fails in Barbados.
What is the necessary Internet connection to implement this setup without comprising bandwidth.
Does trust relationships utilise more bandwidth that using Active Directory sites and services.
Do I have to implement both of these services or just one.
Could someone guide me on how I can implement this as I am not sure?
Thanks very much for your help
