You can use TCP/IP with MS Client, just choose it from the MS Client
setup [1]. The net drivers can be loaded high if you need to conserve
conventional memory. If your NIC isn't on the supplied list, see [2].
Then add server capability by modifying system.ini for file and
printer sharing and adding 'net start server' to the autoexec.bat file
[3] and upgrade net.exe by running WG1049.exe or NNET.exe [4].
Set up your shared resources on the DOS servers with netshare [5].

to give every will-to-live the reverence for life that he
gives his own. - Albert Schweitzer
