PRB: Receive Packet Over IPX on a Token Ring Network (194634)
The information in this article applies to:
- Microsoft Win32 Device Driver Kit (DDK) for Windows NT 4.0
This article was previously published under Q194634 SYMPTOMS
Windows NT 4.0 NDIS drivers that support NDIS Receive Packet might notice
Data Corruption over IPX on a Token Ring Network.
CAUSE
A code defect in NwNbLink caused IPX to only look at the first of multiple
buffers.
RESOLUTION
To temporarily work around this problem, use receive lookahead instead of
receive packet in your driver code. Also, set the Packet size and buffer
size on the Token ring adapter to 2048 or lower to resolve the issue from
an end-user perspective.
MORE INFORMATION
IPX allows packets to span multiple receive buffers. Token Ring's larger
packet size allows packets to span multiple receive buffers. Ethernet
packets are smaller and are not effected by this problem. Windows 4.0 NDIS
drivers that support the receive packet algorithm will encounter this
problem over IPX with Token Ring.
