Hello,
I am currently writing a loopback driver for 2 NIC’s. I set up my
TDI_EVENT_CONNECT handler and I ultimately get to the event_connected. All
I do in the event_connected function is change one passed in variable and
then call the original handler. My problem is, is that when I run TDIMon
application it appears the my TDI_ACCEPT irp times out and the incoming
connection is ultimately dropped. Can anybody tell me why? Does the
‘original’ handler set up the TDI_ACCEPT irp properly and is there anything
I must do after I call the original handler (other than the fact of ensuring
I return MORE_PROCESSING_REQUIRED)? Thanks in advance
/Loren

Do you hook the TDI_ACCEPT irp passed by original event handler?

Hi there,
I’m not sure what you mean by ‘hooking’ the TDI_ACCEPT IRP. Is the
AcceptIrp already initialized and built by the time MY event handler get’s
called?

NIC drivers have nothing to do with TDI. They are NDIS miniports.
