Adjusting Timing and Retry Parameters for Microsoft TCP/IP
In some cases, you may want to adjust the timing and retry parameters
used by the Microsoft TCP/IP protocol. For example, if an MS-DOS
workstation is not using the messaging service, each print job it sends
via Microsoft TCP/IP could result in a lengthy broadcast stream as the
server tries to send a job completed message. By adjusting the timing
and retry parameters for Microsoft TCP/IP, you can reduce this
broadcast stream significantly.
To adjust these parameters, use the following entries in the
PROTOCOL.INI file:
bcasttimeout:n
This option specifies the number of timer ticks that may occur during
a NetBIOS name query or registration before the broadcast attempt
fails. (There are 55 milliseconds per timer-tick.)
The range is 4 to 51; the default is 5.
bcastretry:n
This option specifies the number of times to retry NetBIOS name
query or registration.
You may specify any number greater than 0; the default is 3.
tcpretries
This option specifies how long the workstation continues attempting
to send a packet. The range is – 17; the default is 8. Generally, you
should not use a value lower than 8, which equates to about one
minute. Higher values allow more time for repeated attempts to send
the packet, up to a maximum of about fifteen minutes.
Microsoft TCP/IP and the Sockets Interface
If your LAN Manager installation includes the TCP/IP utilities, the files
SOCKETS.EXE, WSOCKETS.DLL, and WIN_SOCK.DLL are
included in the NETPROG subdirectory of your LAN Manager root
directory to enable communications between utilities and the TCP/IP
protocol.
Both WSOCKETS.DLL and WIN_SOCK.DLL exist to support utilities
for Microsoft Windows; WIN_SOCK.DLL provides backward
compatibility for applications using earlier versions of the Windows
operating system. To use sockets, it must be specified in the [sockets]
section of the TCPUTILS.INI file, and the protocol must be loaded.
The TCPUTILS.INI File
The TCPUTILS.INI file is created by the TCP Setup program. The
default values provided by TCP Setup will probably meet your needs.
However, if you decide to change the file, be sure to make a backup
copy of it first.
