Got a problem I hope somebody can help with: I'm trying to run PC/TCP (Rev 2.05) with LAN Manager over NDIS. This works fine when LM doesn't use TCP/IP for its transport. LM can run over several stacks, including XNS, NBP, TCP/IP and DLC. When LM uses TCP/IP, ie there are 2 TCP/IP stacks over NDIS, LM fails. Does NDIS support dual TCP/IP stacks? Is there a work-around for this? david@hpss2.sgp.hp.com

An NDIS driver sorts packets between stacks by offering them to the stacks in turn. When a stack takes the packet, that's it. The packet is gone. Running two TCP/IP stacks over an NDIS driver will always create some problems, as some packets, intended for both stacks, will only reach one. Still more lossage will be caused by one stack erroneously accepting packets intended for the other. With two stacks of the same type and the same IP address, identifying packets is a problem. The usual result of this is that the stack loaded last gets all the packets.

Does NDIS support dual TCP/IP stacks? Is there a work-around for this?
NDIS does not guarantee that it can pass an incoming packet to more than
one protocol stack, so that's your first obstacle. Your second obstacle
is that you need two IP addresses for the PC, if you propose to run two
separate IPs. I'd recommend that you get our RFC 1001/1002 NETBIOS
product (ask for 2.05 pl 1, it will be out in a little while with several
important bug fixes) and run LM on it, and the PC/TCP stack instead.

In the meantime perhaps you could share with us what NB clients you have managed to get running on top off this; in particular howbout Ms' LM-2.0 and HP lm/x clients (msdog versions). Thanks.
