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 \\\ 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
 Quit Windows for Workgroups.  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 \nwlink.386 nwlink.old where  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  Insert the enclosed WG1027 disk in the appropriate floppy disk drive.</li>  To copy the file to the Windows SYSTEM subdirectory, type the following at the MS-DOS command prompt and then press ENTER copy :\nwlink.386 where is the floppy disk drive containing the WG1027 disk and 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 </li></ol>
