Undocumented Program Neighborhood Command Line Switches
Nearly every professional working with Citrix Presentation Server knows about Program Neighborhood (PN), and some may even use it frequently. It was first introduced in MetaFrame 1.8 and is used to start published applications from one or more server farms. In PN you can either configure individual applications or define application groups. The latter are simply lists of published applications which PN pulls from a designated Presentation Server and displays in its UI.
