I have 6 x sites located all around the land down under. All 6 sites are linked via a meshed VPN network and can see each other.
Now, in Head Office i have 2 x AD Servers (1 backup) on the one domain. All others have their own servers on their own domains.
Head Office - 2008R2 Domain - office1.local (30 users) Branch Office 1 - 2008R2 Domain - office2.local (10 users) Branch Office 2 - 2008R2 Domain - office3.,local (10 users) etc etc
Each server in each branch holds a lot of file storage and staff want access to this quickly so servers must reside in each branch locally.
As i am about to replace all the hardware in all the branches (Servers and Desktops) i have the ability to change things hopefully to make it better.
What is the best scenario in terms of Domain setup? Should i keep them all separate domains? Should i make the branch servers secondary AD servers to the main one in Head Office? Should i put all the PC's on the Head Office domain and have them replicate from there?
What's the best practice for such a Domain Network?
Looking forward to your kind assistance.
