In a Windows network, the computers are only addressed via their names.
Multiple computers can be organized into groups, and multiple groups can be
grouped further as name rooms scopes. The names used must be known
throughout the network for all computers to be able to access the resources
of the others. NetBIOS computers issue their names into the network at
regular intervals to eliminate the necessity of maintaining tables of known
names on each computer.
The names publicized in this manner should, of course, be collected and made
available at a central location in the Windows network. If two Windows
networks are to be connected using a router, then such a name collection
point, a so-called NetBIOS name server (NBNS), must be present on both
sides.
A WINS server (Windows Internet Name Service Server) can be installed
in the network for this purpose.
However, a second option is also available, since many Windows
networks can or must make do without a server of their own: Information
about the names in use can be placed on a “billboard” of sorts, on which
all participating computers only post their names and IP addresses. In this
case, the individual computers are responsible for the consistency of
their names within the network.
The ELSA LANCOM Business offers such a billboard. The interconnection of
Windows networks is thus possible without a server as a result of this simple
realization of the NBNS. The computers in the networks to be interconnected
thus publicize their names and add them to the billboards in the respective
remote networks.
6.6.2 Handling of NetBIOS packets
The highly verbose nature of Windows computers can result in high charges
for dial-up connections, as each NetBIOS packet containing name
information automatically launches a call establishment (e.g. to a previously
set up ISP). The connection remains permanently established due to these
packets, resulting in high connect charges without the transfer of actual user
data.
An ELSA LANCOM Business can either route or spoof the NetBIOS packets to
prevent the establishment of unnecessary connections:
In the NetBIOS module, it is possible to specify the remote stations to
which the name information should be transferred via NetBIOS to ensure
