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.
