Windows 2003 Active Design

Hi,

My Company is going to design Active Directory so assistance on it.
AD Scnerio :
5 Locations :
Location A – 800 users
B – 100 Users
Location C – 100 Users
Location D – 100 Users
Location E – 100 Users

Right now there would not be any connectivity between these locations but it would be next month.

Now I want to set up Windows 2003 DC, ADC, DNS, DHCP, File and Print Servers.

Can someone assist me how I will design this structure as early as possible.

Thanks and Regards,

Anurag
