Hello,
I want to know exactly what the netbios-ssn port 139 does??
Is it related to the security of the PC itself?
If I disable all incoming and outgoing ports (139) on the firewall, what will be the impact?
I noticed when I type the netstat command in cmd, there are strange lines with the remote address of one of the PCs connected to my network using port 139. Is this a form of attack from the external PC or is it just 'normal' to see these lines (2 lines)?
Thanks
Configuration: Windows 7 / Safari 534.13

Hello,
this service is simply one of the two ports used to access Microsoft's network services (shares), the other being 445.
this port should be blocked in all firewalls to prevent the Windows network from being directly accessible from the internet, as it would be a major security flaw.
to access network services from the internet, a secure connection is opened in a VPN.
