RE: Windows examples failed to start using mellanox card

Hi Robert,

Did you set the registry key (DevxFsRules) in the Windows registry?

https://docs.nvidia.com/networking/display/winof2v290/Configuring+the+Driver+Registry+Keys

If not, can you try setting it to the value (0xFFFFFFFF) and see it the issue still occurs after adapter restart?

Thanks,

Tal.
