SYMPTOMS
You receive this error while trying to access voice files from a shared
LAN Manager server directory using VPLAY.EXE:
810 Unexpected Network error - Abort,Retry,Fail
The keyboard freezes and you must hard boot to resume.
CAUSE
Concurrent operations being performed by the Sound Blaster Pro card and
network adapter card create a timing conflict.
Protocol analyzer traces show this sequence:
- The client sends a Server Message Block (SMB) C read byte range.
- The server responds with an SMB read byte range response.
- The server sends NETBIOS data frames until failure occurs.
- The client fails to respond to the server; the redirector
receives no acknowledgment due to a transport/media access failure.
- The system returns then fails and generates a NET 810 error.
RESOLUTION
COMNDIS.COM is a terminate-and-stay-resident (TSR) program (included on
your LAN Manager 2.2 installation disks) that prevents multiple processes
from accessing the adapter card while it is handling an
MS-DOS command.
Run setup and install COMNDIS.COM into the \LANMAN.DOS\NETPROG directory.
To Autoexec.bat, add the line
where X is the interrupt setting used by the installed network adapter.
Add this after netbind, if present, and before netstarting the
workstation.
