PCs and the VisionFS server communicate using the SMB protocol, which runs over NetBIOS.
Technically, NetBIOS can run over multiple network transports, for example NetBEUI, IPX/SPX, and TCP/IP. In fact, any number of transports could be used simultaneously.
To connect to a VisionFS server, a PC requires a TCP/IP stack that supports the NetBIOS protocol. Both Windows 95 and Windows NT are supplied with a compatible TCP/IP stack. A version for Windows for Workgroups is distributed with VisionFS, and is available from the Microsoft web site, www.microsoft.com.
TCP/IP stacks from other vendors will work if they support the NetBIOS interface. You might find that although a particular PC can communicate with another PC, it can't connect to a VisionFS server. This might be because the PCs are using NetBIOS over NetBEUI or another network transport. In this case, the TCP/IP stack does not fully support the NetBIOS interface.
VisionFS can coexist with other file and printer sharing programs on the UNIX server (such as Samba) without customization, as long as those programs don't conflict with VisionFS as the primary NetBIOS over TCP/IP (NBT) application.
You can set up VisionFS to work alongside other NBT applications by designating one as the primary and the others as secondaries.
PCs can run more than one file and printer sharing client at the same time. For more about allowing multiple NetBIOS applications, see ``The possibilities with VisionFS''.
