There is a mismatch in the sort order between the way in which results are displayed in ISPF option 3.4 and the way in which they are displayed within a dataset folder under CMN ZDD/ MS Windows Explorer.
TeamTrack server is running as a Windows service (IIS) and is using the ZDD API to interact with ZMF. Windows services run as Windows session 0, and have an invisible desktop since they can run when nobody is logged on. ZDD has an instance of ZosNet running for each Windows session (each desktop). The instance of ZosNet that services session 0 for services also runs as a Windows service.
