If you wish to use the TCP/IP protocol, each computer on the network that will run Accounting Plus in multi-user mode must be assigned an IP address. An IP address is a set of numbers that identifies each computer on a network that uses the TCP/IP protocol. These numbers can be assigned manually or by using a server.
These instructions will help you set up TCP/IP to a certain extent; however, the choices you make for configuring your TCP/IP connection to your network depend upon how your network is set up. If someone else set up your network connection, you should consult that person for assistance here. You (or the person who set up your network connection) might also find it helpful to speak with your Internet service provider (ISP) to learn how you can receive permanent IP addresses for each of your computers. (Keep in mind that if your computers are assigned IP addresses only when they have an active dial-up connection to the Internet, your computers will encounter various problems communicating to each other when you're using Accounting Plus-unless those computers are always connected to the Internet while Accounting Plus is in use.)
