Networking Protocols

The TCP/IP protocol is the standard used on the Internet and most LANs. It has become increasingly popular for use in all kinds of networks in just the past few years. For example, early versions of Windows NT would install the IPX/SPX protocol by default. Starting with Windows NT 4.0, the default became TCP/IP. This has stayed the same for Windows 2000/XP and Windows Server 2003.

NetWare's legacy protocols (IPX/SPX) aren't used a lot anymore, since NetWare adopted TCP/IP a few years ago. Unless you have an older version of NetWare that still uses IPX/SPX, it would be a good idea to upgrade the NetWare servers to at least version 5.0, which does support IP.
