SUMMARY
=======
Question:
When using the LAN Manager version 1.01 NetBIOS, we periodically receive a
NetBIOS return code 09 when sending a MSG.SEND.DATAGRAM (A0). A code 09 is not a
legitimate return code according to the IBM technical reference Token-Ring
Network PC adapter manual. What should we do when this occurs?
Response:
This error comes from NetBEUI as it runs out of resources. You should increase
the following parameters in PROTOCOL.INI in the [netbeui] section, as follows:
1. If you are using the Mnetb/Mdlc stack (for more information, see the
"Microsoft LAN Manager 1.0 Network Device Drivers Guide")
Min Max Default
--- ---- -------
tx.u.buffers 2 32 4 + 1/4(commands=)
where:
commands 1 255 32
Tx.u.buffers controls the number of buffers allocated for the UI frame
including datagrams, status queries, and session establishment frames.
2. If you are using the NetBEUI stack (for more information, see the
documentation enclosed with the release notes dated August 23, 1989):
Min Max Default
--- ---- -------
datagrampackets 2 1000 2 packets
looppackets 1 1000 1 packets
Datagrampackets controls the number of data descriptors to allocate for
packetizing NetBIOS datagrams into UI frames.
Looppackets controls the number of packets looped back on the workstation.
This parameter will affect the workstation issuing MSG.SEND.DATAGRAM if it
has also put out RECEIVE.BROADCAST.DATAGRAM. It will receive its own datagram
through the loop back in NetBEUI.
