IPX may not work, or data corruption may occur, with a receive-packetdriver when a token ring packet spans multiple receive buffers. Datacorruption is likely when the Receive buffer size on the client Windows NTcomputer is smaller that that of the Maximum transmit size of the WindowsNT server computer.
NOTE: The data transfers may seem to work but the data is corrupted if theNDIS packets are large enough to be split among receive buffers.
The IPX protocol allows packets to span multiple receive buffers, but onlytoken ring packets are large enough to do so. NDIS 4 token ring drivers,such as Ibmtrp.sys, that support the ReceivePacket function may encounterthis problem.
