2.8.4  LAN Manager Basic

   When you set up Windows for use with LAN Manager Basic (all versions), the
   following entry is added to the [386Enh] section of your SYSTEM.INI file:

   network=*dosnet, *vnetbios, lanman10.386

   See the SYSINI.WRI file for more information on this entry.

   Network software based  on LAN Manager  Basic, or on  LAN Manager Enhanced
   without full API support, must not be loaded  in the high memory area (the
   first 64K of extended memory).

   You need  to  modify the  LANMAN.INI  file in  your  network  directory to
   prevent the network  from loading in  the HMA.  Find all  lines that begin
   with redir and add the following command-line option to each:

   /HIMEM:NO
