It needs to be changed in the DCS configuration file and in the DCS utility file. It should also be changed in each DCS configuration that refers to the station. DCS gets it "Station Name" from three sources. In the actively running .cfg file under Equipment/Nodes, and in DCS Configuration (Station Name). In addition, DCS is presenting the user with title/name from Log Editor. This would require the user to edit the configuration file used for CMED (Generic Log Editor) and reflect name changes there as well.
