I need your valuable suggestion in deploying Exchange 2007 in geographically dispersed sites in a domain.
Here is the scenario
I have three different locations like X, Y and Z. There are around 1000 employees working at X location and 100 are located at Y and Z locations. X is my company head quarters and wanted to host my PRIMARY Exchange and Windows 2003 Domain controller. RPC over HTTP will be configured for client’s outlook access. All the sites got interconnected with 2MBPS leased line each.
