Introduction
------------

When you are using the Windows for Workgroups version 3.11 NWLINK.386
file to connect to a network that uses a Cisco router, the following
problems may occur:

 - Windows for Workgroups workstations configured with the "IPX/SPX
   Compatible Transport with NetBIOS" option cannot communicate across
   a Cisco router when both Novell(R) routing and DECnet(TM) routing
   are enabled.

   -or-

 - A Windows for Workgroups workstation displays the "Error 51:
   Failure to Connect" message in response to the NET USE
   \\<SERVER>\<SHARENAME> COMMAND.

These problems occur when NWLINK.386 does not correctly handle certain
Cisco router addresses that begin with the letter A. Any address with
the high-order bit set on an end or intermediate system results in
NWNBlink truncating the routing address, which causes the network
connection to fail.

The WG1027 disk included with this Application Note contains a revised
NWLINK.386 file that corrects this problem.

To install the new NWLINK.386 file
----------------------------------

1. Quit Windows for Workgroups.

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

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

3. Insert the enclosed WG1027 disk in the appropriate floppy disk
   drive.

4. To copy the file to the Windows SYSTEM subdirectory, type the
   following at the MS-DOS command prompt and then press ENTER

      copy <drive>:\nwlink.386 <destination>

   where <drive> is the floppy disk drive containing the WG1027 disk
   and <destination> is the drive and directory of your Windows SYSTEM
   subdirectory.

   For example, if the WG1027 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:\nwlink.386 c:\windows\system
