Chapter Five: Minimizing ISDN Charges Spoofing NetBIOS services 68
Spoofing NetBIOS services
The NetBIOS protocol is used by Windows 95/98/NT to support Microsoft Windows Network Neighborhood,
the MAP NETWORK option in Windows Explorer, and various DOS-based networking commands (such as
net use, net view, and net logon). To maintain these services, NetBIOS regularly exchanges bookkeeping
messages between connected systems. This can cause increased ISDN charges as the line is brought up just to
transfer these messages.
The DIVA LAN ISDN Modem provides several options that let you choose the level of NetBIOS support you
want to maintain.
• All: The DIVA LAN ISDN Modem forwards all NetBIOS traffic to the remote site. No cost savings is
achieved.
• Intelligent: The DIVA LAN ISDN Modem spoofs (replies to without forwarding) all unnecessary traffic
NetBIOS messages to reduce usage of the ISDN line. This option provides full support for all Network
Neighborhood functions.
• Minimal: The DIVA LAN ISDN Modem reduces NetBIOS traffic to a minimum. This options does not
support Network Neighborhood functions. However, it does provide support for the MAP NETWORK
option in Windows Explorer and DOS-based networking commands such as net use, net view, and net
logon.
• None: The DIVA LAN ISDN Modem discards all NetBIOS traffic. NetBIOS services are not supported
across the ISDN link.
