How to Install RAS/LAN Manager on Dual 720K Floppy Disks (78359)






This article was previously published under Q78359

SUMMARY

This article discusses how to successfully load and start Remote Access Server (RAS) on a LAN Manager version 2.1 enhanced DOS workstation from two 720K floppy disks. This procedure is primarily intended for use with older laptop machines with dual 720K floppy disk drives and no hard drive. This configuration should also run successfully from a machine with a single floppy disk, although it will involve some disk swapping.

This configuration requires that LAN Manager 2.1 and RAS be successfully installed on a DOS workstation before copying to dual 720K disks. This must be accomplished by installing an enhanced LAN Manager 2.1 DOS workstation and the DOS RAS service. Additionally, the RAS service on the workstation must be correctly configured for the modem on the machine with the 720K disk drives because the Setup program for RAS will not be included on these floppy disks.

INSTALLATION INSTRUCTIONS

To begin the installation, format one 720K floppy disk as a system disk (FORMAT /S) and label it appropriately (for example, RAS Startup). Format a second floppy disk and label it appropriately (for example, RAS Work). The following discussion assumes that the LAN Manager enhanced workstation has been installed to the C:\LANMAN.DOS directory. If not, make the necessary substitution in the following discussions.

The files will be copied from the appropriate LAN Manager directory on the hard disk to the same directory on the appropriate floppy disk. For example:
   copy c:\lanman.dos\comdev.ini a:\lanman.dos\comdev.ini
				
The format of the directory structure and associated files on the floppy disk drives is listed below. Copy the listed files from the appropriate directory on the hard disk drive to the same directory on the floppy disk drive. It is not necessary to copy the CONFIG.SYS and AUTOEXEC.BAT files from the hard disk drive because they will need to be created in a specific format. All unnecessary files have been removed. The main purpose of these floppy disks is to allow access to a network via RAS on a machine that does not have a high-density disk drive or a hard disk. There is sufficient space on each of the disks to add in necessary DOS commands and any other desired utilities disk space will allow.

RAS Work Disk (Disk 2)

The following files listed in the first column must be included on this disk. The second column lists the location of the file from the hard drive. The LANROOT directory is assumed to be C:\LANMAN.DOS; substitute as appropriate.

MODIFICATIONS TO SYSTEM FILES

The CONFIG.SYS file, shown below, resides on disk 1 and is the minimum configuration required to run RAS and LAN Manager 2.1 from two 720K disks. Other devices can be added as space permits.
   FILES=30
   BUFFERS=10
   LASTDRIVE=Z
   SHELL=A:\COMMAND.COM /P /E:512
   DEVICE=A:\LANMAN.DOS\DRIVERS\PROTMAN\PROTMAN.DOS /i:A:\LANMAN.DOS
   DEVICE=A:\LANMAN.DOS\DRIVERS\ASYNC\ASYMAC.DOS
				
Construct the AUTOEXEC.BAT file as follows. It also resides on the root of disk 1 and represents the minimum configuration needed. Other features may be added.
   @ECHO OFF
   PATH A:\;B:\;A:\LANMAN.DOS\NETPROG;
   PROMPT $P$G
   SET COMSPEC=A:\COMMAND.COM
   B:
   NET START WORKSTATION
   CALL RASLOAD
   A:
   RASPHONE
   B:
				
Edit the LANMAN.INI file on disk 2 as follows:

  1. In the [workstation] section, the lanroot entry should read:
          lanroot = A:\LANMAN.DOS
    						
  2. In the [services] section, specify the new location of the LAN Manager services as follows:
          chknet        = B:\chknet.exe
          minses        = B:\minses.exe /n
          workstation   = B:\netwksta.exe
          messenger     = B:\msrv.exe
          netpopup      = B:\netpopup.exe
          encrypt       = B:\encrypt.exe
    						

NOTES

There are several disadvantages of running this particular configuration. All invocations of RASPHONE must be done from drive A. All net commands (NET LOGON, NET USE, NET SEND, and so forth) must be done from drive B. If these commands are run from the incorrect drive, an error message similar to "unable to open message file xxxxx.msg" will be displayed. This is not a harmful error; it means only that it is necessary to switch to the root of the other floppy disk and retry the command.

If any modification to the configuration of this setup is required (such as switching modem configurations), it will be necessary to modify a fully installed DOS LAN Manager enhanced workstation from a hard disk, and copy the modified files to the appropriate floppy disk.
