    This was Disc 2 as part of the Netware 5.1 demo. The contents of the disc
    doesn't look specific to the demo - probably the same as any other 
    January 2000 clients CD.
    
    Content looks to be:
        ZENworks Starter Pack: October 1999
                    NT Client: 4.7
                    9x Client: 3.2
               DOS/Win Client: 2.71
