The GPIB-ENET/100 box does not ship with the driver. You will need a driver for it. To order it call NI or go to http://ni.com/catalog. You will need version 1.2 for Windows NT\2000 or version 1.7 for Windows 98/95/Me.
You can find "Getting Started" manuals at http://digital.ni.com/manuals.nsf/web%2Fbyproductcurrent?OpenView&Start=1&Count=500&Expand=6.9#6.9.
