Upgrading a Shared Windows 3.1 Network

• Microsoft Windows operating system versions 3.1, 3.11

SUMMARY

When upgrading a shared network installation (using the SETUP /N command) from Microsoft Windows version 3.0 to Microsoft Windows version 3.1, the Windows 3.0 files contained in the shared directory must be removed completely and replaced with files from Windows 3.1 before performing the upgrade for the Windows user directories.

The Windows 3.1 SETUP /N command can only be used to upgrade Windows 3.0 user directories if the directories were originally created using the SETUP /N command from the Windows 3.0 program.

RESOLUTION

Perform the following steps to correctly upgrade a Windows 3.0 shared network to Windows 3.1:

1. All users on the network exit from Windows.

2. Log onto the network as supervisor.

3. Remove all the read-only attributes on the Windows 3.0 files in the shared directory using the MS-DOS ATTRIB command or Novell FLAG command. (The shared directory was created using steps 1-9 on page 553 of the "Microsoft Windows User's Guide" for version 3.0, and should contain between 282-286 files.)

   From the Windows Shared Directory MS-DOS Prompt, type the following command:

         attrib -r *.*
   

         -or-
   

         flag *.* rw
   

   Note: The flag *.* rw command is for Novell users only.

4. If no third-party applications, DLLs, or drivers have been installed (for example PC Tools, Norton Desktop, drivers from OEMs or the SDL), and their files do not reside in the same shared directory as Windows 3.0:

   a. Delete the Windows 3.0 files.

         -or-
   

   b. Move the Windows 3.0 files to a new location. (If these files

         are moved, make sure they are not placed in a directory that is
         in the path or on a Novell search drive.)
   

   If ANY third-party applications, DLLs or drivers have been installed (PC Tools, Norton Desktop, drivers from OEMs or the SDL) and their files reside in the same shared directory, perform the following procedure to remove only those files that were provided by Windows 3.0:

   a. Place the Windows 3.0 Disk 1 in a floppy drive.

   b. Make the floppy drive the current MS-DOS drive.

   c. At the floppy drive MS-DOS command line, enter the following

         MS-DOS command
   

            FOR %A IN (*.*) DO DEL x:\path\%A
   
        where "x:\path" is the network drive and path to the Windows 3.0
        shared directory.
   
     d. Repeat steps a-c above for each of the original Windows 3.0
        floppy disks.
   
      NOTE: In a small number of cases, third-party display drivers will
      either be using the 386grabber (*.gr3) and 286grabber (*.gr2) files
      supplied by Windows 3.0 or replacing the Windows 3.0 grabber files
      with their own and using the same filename. In these cases, Windows
      3.1 Setup will not update the SYSTEM.INI file for the Windows 3.1
      grabber files (*.3gr and *.2gr) and you will get errors upon
      loading Windows 3.1 after upgrading the user if you delete these
      files. To be absolutely safe, copy the *.gr2 and *.gr3 files in the
      shared Windows directory to a floppy or separate directory before
      performing the above procedure, and copy them back if needed.
   
   

5. Follow the instruction on page 9 of the "Microsoft Windows Getting Started" guide for version 3.1 to place the Windows 3.1 files into a clean Windows shared directory by executing the following command:

           SETUP /A
   
      NOTE: If you have a network requiring a workstation driver update
      for Windows 3.1, you may want to upgrade the workstation network
      software before completing the next step. For example, Novell users
      should update the IPX to 3.1 and NETX to 3.26 or IPXODI to 1.2 and
      LSL to 1.21.
   
   

6. Have each user follow the instructions on page 8 of the "Microsoft Windows Getting Started" guide for version 3.1 to upgrade the Windows user files to Windows 3.1. When prompted for the directory to install to, specify the location of the existing Windows 3.0 user directory. (User directories generally have less than 20 files in them and do not have a subdirectory called SYSTEM.) This will upgrade all necessary files and Windows 3.1 will now be operational.
