There are two ways to start the NPN Admin program. If the NotePager Net Server is running, there should be a pager icon in the Windows system tray (bottom right corner of the screen, next to the clock). Click on the pager icon and you will see a popup menu. Choose 'PG Admin' from the menu. NPN Admin can also be started from the Windows start menu. Choose 'Start' > 'Programs' > 'NotePager Net' > 'NotePager Net Admin'. NPN Admin will start.
To exit the NPN Admin program, either click on the 'X' control on the NPN Admin window, or right-click on the 'NotePager Net' object and choose 'Exit' from the popup menu.
