May have fixed this. It was happening logged on to WAC Gateway as administrator & was just affecting the Personal connections list, NOT the shared list. Steps: 1) Removed ALL entries in Personal then closed browser. 2) Reconnected as administrator. The Personal list is populated with what is apparently an entire copy of the Shared connections list. 3) After connecting an entry in the Personal list now gets the correct NetBIOS name appended. Ho hum.. I don't need anything but the Shared list. Can you turn the Personal list off for everyone, including Gateway administrator(s) somehow?
