Tip T501 - The IPX/SPX protocol is mainly used by Netware and other LAN networks.
Fix: If you are not on a LAN, you only need TCP/IP to connect to the Internet - IPX/SPX does not help you. Even if you have a LAN, most LANs use NetBEUI that is the default for Microsoft networks. In these cases you should remove IPX/SPX. Open Control Panel\Network\Configuration, click on IPX/SPX and click Delete. Reboot your computer.
