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
