SYMPTOMS
========

When you use the Banyan Vines client service version 5.5.6 and the IBM Token
Ring driver (IBMTOK.SYS) in Windows NT, Event ID 5002 appears in the Event
Viewer. The description of the system event is:

  The description for Event ID (5002) in Source (IbmTok) could not be found.


CAUSE
=====

This problem occurs when the IBMTOK.SYS driver identifies that any one of the
bits in a particular register (ISRP_LOW) on the network adapter are set. Refer
to Chapter 7 of the IBM LAN Technical Reference regarding ISRP- even. The event
log data indicates that bit 2 is being set. Bit 2 is the access interrupt bit
described as follows:

  When this bit is on, it indicates that a shared RAM violation or an Illegal
  MMIO operation by the computer to an Attachment Control Area register pair
  has occurred. The following conditions will set this bit:

  - Any workstation write to a write protected location in the shared RAM.

  - Any workstation write to the shared RAM mgmt registers (WRBR, WWCR and
  WWOR).

  - Any workstation write to ISRA(even).

  - Any workstation write to a non-zero field of ISRP - odd or ISRA - odd.
  Non-zero Interrupt fields of ISRP - odd and ISRA -odd must be manipulated
  using OR and AND MMIO commands.

Windows NT logs the error and resets the ISRP_LOW byte to 0.


RESOLUTION
==========

A new version of VNS.SYS that resolves this problem is available from Banyan
Support Centers.
