It is recommended that users disable the NetBEUI and IPX/SPX protocols under Dial Up Networking in Windows 95/98. This allows a faster connection to a user's Internet Service Provider. But what are they and why would they be there in the first place? A network protocol is a set of rules that defines how information travels across a network (between a group of electronically linked computers). You could think of them as rules of the road. The difference between two network protocols is like comparing driving in North America where we drive on the right side of the road to Great Britain where they drive on the left hand side. They're two complete different ways of defining the same process. Now consider TCP/IP. That's the protocol behind the Internet : TCP/IP means "Transmission Control Protocol over Internet Protocol." NetBEUI is the network protocol used by Microsoft network systems and IBM's LAN Server systems. It's a small, lean network protocol that's very fast. IPX/SPX refers to a network protocol used by Novell products. IPX means Internetwork Packet eXchange. SPX means Sequenced Packet Exchange. The bottom line is that if you're just connecting to the Internet, you don't need to bother with NetBEUI or IPX/SPX. They're installed as default networks with Windows 95 because "anytime a network adapter is installed, Windows 95 installs Client for Netware Networks which needs IPX/SPX and Client for Microsoft Networks which will load NetBEUI," explained Mathew Fiszer, a CyberWalker adviser, who works at Logicorp in Edmonton. Basically, the install of the two extra protocols prepares you to do corporate networking. They'd be useful if you wanted to dial up your company computer and talk to its network. If your computer doesn't need to talk to a corporate network and the protocols are installed, then they'll be a delay when you go to connect to the Internet. Why? Because when you make a call with your modem, the computer first checks to see if either NetBEUI or IPX/SPX network connections can be made. This takes time. When it can't make these connections it then tries TCP/IP and finally -- after all that waiting -- a connection to the Internet is made.

Should you get a customer who's dialler is dialing what seems like two numbers or a prefix before the number and you can't find anything wrong in dialling properties...
Check the sequence of numbers, If it has a dollar sign in it, it means it is set to use a calling card - just untick that option in dialling properties.
