Tell me the correct protocol if i want to allow windows networked drives between two firewalled computers? I need to submit a form and get approval for open firewall ports and i don't want to ask for more open ports than i need All these machines are running windows xp or later

Note when i say windows networked drives i'm not really sure whether i'm referring to smb or cifs and i'm not entirely clear on the difference between the two protocols

Best Answer

Ports 137-139 are for netbios/name resolution. You will need to access machines by ip address without netbios name Example \\192.168.1.100\share_name opposed to \\my_file_server\share_name

So port 445 is sufficient if you can work with only ip addresses
