PATHWORKS DECnet VxD NDIS exception?

» close window

The Question is:

We are experiencing problems with Pathworks
running on Windows 95 and NT 4.
Basically, we have an intermittent problem with
Pathworks users that run DECNet. Non DECNet
users don`t seem to be affected.
The users will be connected to the VAX and
working normally, when the following Windows
blue screen error occurs simultaneously:-
"An exception OE has occurred at 0028:000001E3
in VxD ---. This was called from 0028:C004BD3C
in VxD NDIS (01) + 00008660. It may be possible
to continue normally"
Users are able to continue, only after re-
booting the PC.
We are running DECNet OSI Phase V, with various
Pathworks versions from 6.0.003 to 7.0.035.
O/S are Windows 95 or Windows NT4 with a mixture
of 3Com Ethernet cards and the Novell Intranetware
client. Some PC`s have TCP/IP, some do not.
The fault can be absent for several days and
then appear several times in one day.
Can you shed any light on where to start

The Answer is :

  Without additional details of the environment, it is virtually impossible
  to determine the cause of this particular problem.
  Some ideas and suggestions:
  - What version of PATHWORKS 32 are you running on the desktop (the PC
    systems running Microsoft Windows 95 and NT 4.0)?  PATHWORKS 32 V7.1a
    was released in October, 1998 -- if you are running an earlier version,
    it may help to update to a more recent version.
  - Are there updated NDIS drivers available for the network adapter in
    the PC system?
  - Has the configuration on the remote host system that is running
    DECnet-Plus (formlery DECnet/OSI, formerly DECnet Phase V) changed in
    any way?
  - Are there any errors logged on the host system?  (Check for device
    errors, as well as for DECnet communications errors and unexplained
    changes to the DECnet counters.)
  - When the error occurs, what application is being used on the PC?  What
    other applications are running on the system?  Is there one application
    that is common to all systems experiencing the problem?
  Please contact the Compaq Customer Support Center for further assistance.
