SPECIAL SITUATIONS

     Using wide range of NETBIOS driver start parameters, as well as work
stations and server programs you can create individual configuration to suit
your needs, that is, to modify or add some parameters in STARTNET.BAT file.

     Consider the most common situations:

1. Network with a large number of stations.

     Since a large number of servers or work stations try to log to the
server simultaneously, the servers resources will be exhausted soon and
further attempts to log with NET LOGIN command will prove unsuccessful. In
this case you should modify:

- NAMES, SESSIONS, NCB parameters of NETBIOS driver
- NAMES server's parameter.

     About the optimum values of these parameters see "LotLAN commands"
(working with NETBIOS drivers).

2. Network with a large number of servers.

     The problems here can arise if a work station is trying to log to a
large number of servers. In this case it is neccessary to increase the value
of the following parameters:

- NETBIOS parameters: NCB and SESSIONS,
- the parameter NAMES of the work station.

    About the optimum values of these parameters see "LotLAN commands".

3. Running software that may access NETBIOS.

     When you run some software simultaneously with network which also uses
NETBIOS names, sessions or NCB, these parameters may prove insufficient to
support network operation. In this case you should modify NAMES, SESSIONS,
and NCB parameters of the NETBIOS driver following the procedures described
in the software manual (see also "LotLAN commands", working with NETBIOS
drivers).

4. Using databases, spread sheets.

     When running database and spread sheet applications under the network
environment, a large number of files are opened simultaneously and you
should encrease the FILES parameter in the server  program. (See "LotLAN
commands" - server program).

A large number of database management programs read/write files by small
portions. That is why we recommend to use LANCACHE program.

5. Using two network adapters and two serial ports on server.

     In this case you should use two NETBIOS drivers and special server
parameters to enable work stations in different type networks to access the
server. There is no need to change work station configuration, but that of
the server has to be modified.

Example: consider STARTNET.BAT file for the server:

NE2000 port=300h irq=5
RS232 port=com2 irq=3 adapters=1
server SERVER /adapters=1

     Here the NETBIOS driver with adapter 0 (by default, ADAPTERS=0) is
loaded first for ETHERNET adapter, and the NETBIOS driver with adapter 1 is
loaded for serial ports. After that the servers program with parameter
ADAPTERS=1 is loaded (ADAPTERS=1 indicates, that support for NETBIOS drivers
with adapters 0 and 1 will be provided).

     For three computer configuration on serial ports (2 servers and 1 work
station) STARTNET.BAT file is the following:

RS232 port=com1 irq=4
RS232 port=com2 irq=3 adapters=1
SERVER SERVER /adapters=1
