I am running a team of two 10 GigE ports on Intel X520-DA2 network card. They work well in tandem and achieve the desired throughput. However, I see an intermittent issue whereby WireShark and my own application (using WinPCap) only show the underlying ports, failing to recognize the team adapter.

Details: Intel 17.4 NIC drivers on Windows Server 2008 R2 with all patches. HP DL370 G6 server. RSS enabled on Intel both underlying Intel NICs.

The exact error: Unable to open the adapter (rpcap://\Device\NPF_{401D5903-16E7-41DC-8484-5D96765B9692}). failed to set hardware filter to promiscuous mode

I heard that if you say his name three times, @GeraldCombs shows up to answer Wireshark questions here. – MDMarra Dec 8 '12 at 2:59
The fact that he's a user here is the coolest thing. – joeqwerty Dec 8 '12 at 3:07
Sometimes in the driver properties under device manager there is an option for allowing promiscuous mode. Perhaps this is a hardware limitation though. – SpacemanSpiff Dec 10 '12 at 18:33
@SpacemanSpiff I checked in the Intel configuration sheets, but did not find anything related to this. – GregC Dec 10 '12 at 21:28
Is that card a "CNA" style card? Can you partition it at all? – SpacemanSpiff Dec 11 '12 at 0:35
