Running MS-DOS SHARE with Windows for Workgroups

Summary:

During the installation of Microsoft Access, Setup automatically
inserts the following MS-DOS command in the AUTOEXEC.BAT file:

   <MS-DOS directory>\SHARE.EXE /L:200

If you are running the Microsoft Windows for Workgroups operating
system, it is recommended that this SHARE command be removed.

More Information:

Windows for Workgroups has its own sharing mechanism (VSHARE.386),
which is loaded with Windows (there is an entry for it in the
SYSTEM.INI file). If you load SHARE before running Windows for
Workgroups, VSHARE will not load. Everything should work correctly,
but the number of locks available to you will be limited by the number
specified when SHARE was loaded (determined by the /L parameter--the
default is 20). VSHARE, on the other hand, dynamically allocates the
number of locks available on demand. The number of available locks is
very important if your Windows for Workgroups machine is going to act
as a server.
