Situation: The protocol you selected, after selecting Multi-user Access in the Sign-on window, isn't available on your computer.
Solution: Select another protocol. NetBIOS, NetBEUI or TCP/IP protocols must be installed on the computer where MYOB Accounting Plus is installed if you wish to open Accounting Plus in multi-user mode. If your system currently doesn't support one of these protocols, you must install (or re-install) one of them.
