Due to this you would want to leave them functioning. Just do your best to secure access to file shares ie: don't allow inbound traffic through your router for port 137, 138, 139 and 445, use passwords and so on. Cheers, Don Hello Emre,

That would entail not allowing port 137, 138, 139, and 445 to traverse subnets. Port 135 is the DCERPC service. Cheers, Don Hello Emre,
