DLC Interface with IBM PC LAN NetBIOS Stack and MS-DOS LM (68426)


The information in this article applies to:

  • Microsoft LAN Manager 2.0
  • Microsoft LAN Manager 2.1
This article was previously published under Q68426

SUMMARY

While it is true that MS-DOS LAN Manager versions 2.0 and 2.1 do not expose the DLC interface, these versions will run on top of IBM's NetBIOS stack. This article explains how to configure them.

MORE INFORMATION

The IBM PC LAN program installs this in your CONFIG.SYS file: 
   DEVICE=C:\PCLP\DXMA0MOD.SYS
   DEVICE=C:\PCLP\DXMC1MOD.SYS
   DEVICE=C:\PCLP\DXMT0MOD.SYS O=N ST=10 S=25 C=22 ES=2 EST=2
   IFS=C:\PCLP13BS\REDIR.SYS
   INSTALL=C:\PCLP13BS\IFSFUNC.EXE
Use these steps to get MS-DOS LAN Manager version 2.0 or 2.1 to use the DLC layer:

  1. Install MS-DOS LAN Manager as usual.
  2. During the install process, select the protocol stack you want to use.
  3. After exiting Ms-DOS LAN Manager, remove any instances of device drivers from CONFIG.SYS for MS-DOS LAN Manager.
  4. Remove both the "IFS=" line and the "INSTALL=" lines from your CONFIG.SYS file. It is not necessary to load the IBM LAN requester.

    At this point, your CONFIG.SYS file should look like this: 
          DEVICE=C:\PCLP\DXMA0MOD.SYS
      DEVICE=C:\PCLP\DXMC1MOD.SYS
      DEVICE=C:\PCLP\DXMT0MOD.SYS O=N ST=10 S=25 C=22 ES=2 EST=2
  5. Remove NETBIND from your AUTOEXEC.BAT file, because there is nothing to bind now.

    Because the Protocol Manager is not loaded, NETBIND is not needed and the contents of PROTOCOL.INI are irrelevant.
Microsoft has confirmed that this configuration works correctly.
