Re: two network adapters on a dual processor - on interrupt routing

Check the interrupt configuration of your devices in system BIOS.
NDIS drivers can call any native Windows system functions, but such a
driver cannot be certified by WHQL. So you can only use functions like
KeGetCurrentProcessorNumber() for test purposes.
NdisGetCurrentProcessorCounts() returns the current processor number in
the 'pIndex' parameter, but you cannot call this function from an ISR.

Hello,
I have two network cards on an Inte lXeon, Windows server 2003.
Both nics (network cards) are recieving packets continously.
I was told that windows would ensure that interrupts from each nic
would go to different processors. Do you think this would be the
case?.
The task manager shows very little activity in second processor and
lots in first.
In any case, I want to find out which processor the ISR is running on.
I don't think an NDIS driver can include/call ntddk apis (like
KeGetCurrentProcessorNumber). Is there any NDIS call which would tell
me the current processor?.
Thanks for your time.
