                        Chapter 6      Desktop Info Servers Installing a Dual Server Desktop Architecture       Desktop Info Server Architecture Overview The Desktop Info Server architecture uses a Master Info Server and one or more Desktop Info Servers  to share the duties normally performed by a single Info Server. Alerts appear for operators on a dual  server desktop (DSD). The main functionality of the DSD is the same as a standard desktop; for  operators, the DSD functions identically to a standard architecture. D

                        Chapter 6      Desktop Info Servers Installing a Dual Server Desktop Architecture       If you specify installation of a Dual Desktop architecture, you are prompted as to whether the Info Server  that you are installing is the Master Info Server in the DSD architecture. You are also asked whether you  want to install a DSD on the current host. You can install one or more Dual Server Desktops. You can install the DSDs on the same host that is  running the Master Info Server in the DSD configurati
