Networks based on Microsoft LAN Manager can be installed in either basic or enhanced versions. All versions of LAN Manager support MS-NET and NetBIOS functions. However, if you are running the enhanced version of LAN Manager with the API option, your applications can also use a powerful set of networking functions.
Non-Windows applications can call networking functions by linking with DOSNET.LIB, a static-link library provided with the network software. Windows applications, however, must use two dynamic-link libraries (DLLs), NETAPI.DLL and PMSPL.DLL, distributed on every workstation with the enhanced version of LAN Manager 2.0. (These DLLs do not run with LAN Manager 1.x or with the basic version of LAN Manager 2.0.)
