When you try to create an adapter team in the Broadcom Advanced Control Suite (BACS), you may receive an error similar to the following:
[0006] Broadcom BCM5708C NetXtreme II GigE (NDIS VBD Client)
#2 does not support teaming.
Please select an adapter with NDIS 6 driver.
This error often occurs on a server with antivirus software installed, and it does not typically indicate a problem with the adapter itself. If the installed antivirus software includes a network filter driver, this driver binds to the adapter's miniport driver, and the Broadcom Advanced Control Suite (BACS) does not correctly handle this condition. Creating a team is therefore not possible.
The only known fix at this time is to remove the antivirus software from the server, create the adapter team, and reinstall the antivirus software. Simply disabling the antivirus software or its network component while creating the team may also suffice, but this is not guaranteed.
