SMB client for Win32 or C#

[macja...@gmail.com]

I'm trying to write a Win32 /.net client to replace a legacy DOS
client-server app. The DOS client communicates with a server side
application using SMB over NBT.
I'm writing in C# and as far as I know there is no SMB or NBT
implementaiton for C#. I've tried building the NBT / SMB packets and
sending over a C# TCP connection, but the problem I've come up against
is that the server responses are contained within TCP ACK packets, and
I can't find a way to read the contents of these packets as the TCP
subsystem discards anything with ACK flag set to 1 and doesnt pass the
payload up to the application.
Can anyone help with this?
Any ideas would be gratefully appreciated.

Win32 accesses SMB over TCP/IP. I haven't seen an option to enable
NetBIOS access since NT 4.0. If you need to work with a DOS system,
I believe you will have to move up to the DDK and use C or assembler
to write network drivers below the NDIS layer to read or write NetBIOS
packets. I hope you have written IP layer drivers before. It is not
easy to do.

I seriously doubt that the DOS app specifically uses SMB over NBT. I
suspect is simply uses the standard Lan Manager style communications without
relying on the underlying implementation. Could you post some of the code,
if you have it, showing the actual communications. If you don't have access
to this code, please post the system requirements for both the client and
server. Don't forget to list any network shares the server is required to
export.
