E3 Admin can be closed without closing E3 Server, via Close E3 Admin option. When this happens, E3 Server continues executing, but no icon appears on Windows Notification Area. In this case, when E3 Admin is not open, error messages appear as message boxes to all logged in (and active) users on the machine executing that E3 Server.

At any time, E3 Admin can be restarted to control the E3 Server currently executing, by simply starting E3 Admin without parameters. The installer also creates a shortcut to open E3 Admin directly.
