With version DS 5.95 and above a new screen is added to the 4.11 server : RollCall
Like DStrace it was used internally for engineering and debugging purposes. The screen shows when WANMAN (at this time, a beta product) is registered with rollcall and DS. Future products will also be registered with Rollcall.
Currently there are no options to disable the Rollcall screen. . Therefore until an option is created that allows Rollcall to be disabled please just ignore the screen.
NDSManager version 1.25 (and above) has been enhanced to distribute the rollcall.
