Unfortunately I don't know the answer to this one. I suspect Thomas Divine would know and hopefully will pick up the thread. (or you can start a new one)

Alireza,

I know that network stack is basically different under Vista, but still
I did not think that changes are so dramatic. I would like to ask you a
question about TDI filters. As far as I understand, they are going to
be pretty useless under Vista - all communications between TCPIP.SYS
and its clients simply bypass it, so that TDI filter that works
perfectly well under XP is nothing more than just a dead code tthat
never get invoked under Vista.

Could you please tell me if my suggestion is correct. Thanks in advance

Regards

Anton Bassov

This is not how NDIS 6 drivers work (we don't even send this OID down to
NDIS 6 drivers). NDIS 6 drivers advertise offload capabilities during
initialization. Furthermore, whatever they advertise is assumed to be "on"
by default. If user wants the driver not to advertise a particular offload
capability, it will do so by setting the standard keyword for that
capability accordingly. If after advertising a capabilities, user wants a
particular capability off, (or back on), miniport driver will get an
OID_TCP_OFFLOAD_PARAMETERS.

Please see the DDK for further information.

-thanks, ali
