TCP/IP-32 May Fail on Token Ring Network with Source Routing (122317)


The information in this article applies to:

  • Microsoft TCP/IP-32 for Windows for Workgroups 3.11
  • Microsoft Windows for Workgroups 3.11
This article was previously published under Q122317

SYMPTOMS

If Microsoft TCP/IP-32 and IPXODI are loaded on a token ring network with source routing enabled, the TCP/IP-32 utilities, such as PING, may fail to locate hosts on the network.

CAUSE

This problem occurs due to incorrect configuration of ROUTE.COM (Novell's IBM-Token-Ring Source Routing Driver with DOS ODI) and incorrectly configured NET.CFG file.

RESOLUTION

To correct this problem:
  1. Copy the ROUTE.COM file to a boot disk from the Novell DOS ODI Workstation Services disk.
  2. Add the following two lines in the AUTOEXEC.BAT after LANSUP.COM or TOKEN.COM and before the protocol stack:

    ROUTE BOARD = 01
    ROUTE BOARD = 02

    NOTE: The BOARD parameter does not refer to the physical NIC. Instead, it refers to the Frame specified in the NET.CFG file.
  3. Add the following two lines in the NET.CFG file (if it is not already present):

    Frame Token-Ring
    Frame Token-Ring_SNAP
