Introduction

If you use the 3Com EtherLink(R) III (3c509) network interface card (NIC) and a 3Com ODI MLID (3C509.COM or 3C5X9.COM) with Windows for Workgroups version 3.11 and Novell(R) NetWare(R) is installed as your secondary network, your system may:

• Stop responding (hang) when you copy large files across the network.

  -or-

• Inadvertently lose network connections.

The updated file allows you to successfully use multiple 3Com NICs with Windows for Workgroups. The updated file ensures that all adapter names are available for binding when multiple ODI drivers are loaded. For example, you can now have the 3c503 and 3c509 drivers loaded so that you can run two NICs on separate networks or send one protocol to one NIC and a different protocol to another NIC.

NOTE: Although you can use multiple different NICs, you cannot use more than one of the same NIC. For example, you can use a 3c503 NIC and a 3c509 NIC, but you cannot use two 3c503 NICs.

The WG1004 disk included with this Application Note contains an updated NETWORK.INF file that corrects binding entry errors with the 3Com EtherLink III 3c5x9 driver. The updated NETWORK.INF uses MLID=*:3C5X9.COM instead of MLID=*:3C509.COM.

To install the updated files

1. Quit Windows for Workgroups.

2. Make a backup copy of the currently installed MSODISUP.386 file by typing the following at the MS-DOS command prompt and then pressing ENTER

         ren <drive>:<path>\msodisup.386 msodisup.old
   

   where <drive>:<path> is the location of your Windows SYSTEM subdirectory.

   For example, if your Windows directory is called WINDOWS and is on drive C, type the following at the MS-DOS command prompt and then press ENTER:

         ren c:\windows\system\msodisup.386 msodisup.old
   

3. Repeat step 2, but substitute NETWORK.INF for MSODISUP.386 and NETWORK.OLD for MSODISUP.OLD. For example, if your Windows directory is called WINDOWS and is on drive C, type the following at the MS-DOS command prompt and then press ENTER:

         ren c:\windows\system\network.inf network.old
   

4. Insert the enclosed WG1004 disk in the appropriate floppy disk drive.

5. To copy the MSODISUP.386 and NETWORK.INF files to the Windows SYSTEM subdirectory, type the following at the MS-DOS command prompt and then press ENTER

         copy <drive>:*.* <destination>
   

   where <drive> is the floppy disk drive containing the WG1004 disk and <destination> is the drive and directory of your Windows SYSTEM subdirectory.

   For example, if the WG1004 disk is in drive A and your Windows directory is called WINDOWS and is on drive C, type the following at the MS-DOS command prompt and then press ENTER:

         copy a:*.* c:\windows\system
