Most Businesses today are spread across the globe. As Network Managers you need to ensure the computers at your Head Office and Branch Offices are monitored alike. You will also need to manage the computers of roaming/mobile users who connect to your network via Internet.
Desktop Central manages desktops that are geographically distributed from a central point. This includes computers that are located in a LAN, WAN and Mobile users as well. In LAN network, each managed computer will directly communicate with the Desktop Central Server for pulling the instructions for performing desktop management activities and to update the status back to the server. Desktop Central has introduced the concept of Distribution Servers to manage computer that are located in remote offices(WAN). This helps administrators to plan and control the bandwidth utilization and associated costs.
The figure below depicts the architecture for managing computers across WAN:
The Distribution Server located at the remote location synchronizes the Configuration/Patch/Software repositories with the Desktop Central Server located at the Main Office at specific intervals. Now the WAN agents installed on the desktops at the remote location can download the patch/service pack/software from the Distribution Server locally within the Remote Office LAN. This mechanism clearly addresses the bandwidth related issues and also improves the efficiency and control-level that network managers/administrators can exercise on the remote machines.
