VMS Help SHOW, USERS, Qualifiers, /NETWORK  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /NETWORK
       /NONETWORK

    Displays all network users in the OpenVMS Cluster environment. To
    restrict the display to users on specific nodes, use the /NETWORK
    qualifier with the /NODE qualifier. When you use the /NONETWORK
    qualifier, all network users in the OpenVMS Cluster environment
    are excluded from the display.
