Title: Avoiding NET2131 Message When Setting Links for DOS Enhanced Station
date: 4/13/90

Copyright 3Com Corporation, 1991.  All rights reserved.

When setting the number of links a DOS Enhanced workstation can handle,
you must correlate two parameters in the LANMAN.INI file:  NUMRESOURCES=
and NUMSERVERS=.  NUMRESOURCES= refers to the number of links the
workstation can handle.  NUMSERVERS= refer to the number of sessions the
workstation can handle.

If you intend to run NetBIOS applications other than LAN Manager, the
NUMSERVERS= parameter must be less than or equal to the NetBIOS
sessions that are supported by the transport protocol.  Also, the value
of NUMSERVERS= must ALWAYS be at least two more than the value of
NUMRESOURCES=.  Otherwise, you will get the following informational
message:

   NET2131: The parameter specified for MaxNCB's (/s:) in LANMAN.INI
   was too small, using xx.

The DOS Enhanced Redirector has overridden your chosen value of NUMSERVERS=
and is now using xx.  This is because the data structures controlled
by the NUMSERVERS= parameter are also used as a generic pool of Network
Control Blocks (NCBs).  The Enhanced Redirector needs at least two NCBs
available in order to perform transaction SMBs (such as remote API calls
to a server).  To prevent you from allocating all of the NCBs to tracking
server information, the Enhanced Redirector will override your parameter
setting, if necessary, to assure that there are least two NCB data structures
more than the value you defined in NUMRESOURCES=.
