However, this can be downloaded and installed on Windows 2000, Windows 2003 and Windows XP versions of the operating system. wntipcfg can be downloaded from here. Install the tool by accepting the defaults and will install under c:\program files\Resource kit\
If there is more than one Ethernet and/or wireless cards on the system then click more info on the tool and click the Down arrow on the list box, a very small scroll bar (not that easily visible unless you care to look carefully) which will have all the Ethernet/Wireless cards listed.
