What port does Windows file sharing use?
Microsoft file sharing SMB: User Datagram Protocol (UDP) ports from 135 through 139 and Transmission Control Protocol (TCP) ports from 135 through 139. Direct-hosted SMB traffic without a network basic input/output system (NetBIOS): port 445 (TCP and UPD).
What port is file sharing?
What Are Ports 139 And 445? SMB has always been a network file sharing protocol. As such, SMB requires network ports on a computer or server to enable communication to other systems. SMB uses either IP port 139 or 445.
What is 1433 port used for?
Port 1433 for TCP is needed to connect to the SQL database instance. By default, SQL will attempt to use 1433. If that port is unavailable, it will automatically choose another port.

Port 139 is used for File and Printer Sharing but happens to be the single most dangerous Port on the Internet. This is so because it leaves the hard disk of a user exposed to hackers.
What are ports 139 and 445 used for?
Port 139 is used by SMB dialects that communicate over NetBIOS. It’s a transport layer protocol designed to use in Windows operating systems over a network. Port 445 is used by newer versions of SMB (after Windows 2000) on top of a TCP stack, allowing SMB to communicate over the Internet.
What is port 3389 commonly used for?
Remote Desktop Protocol (RDP) is a Microsoft proprietary protocol that enables remote connections to other computers, typically over TCP port 3389. It provides network access for a remote user over an encrypted channel.
Why is port 139 open?
If you are on Windows-based network that is running NetBios, it is perfectly normal to have port 139 open in order to facilitate that protocol. If you are not on a network using NetBios, there is no reason to have that port open. That way you are sure that all NetBios traffic originates from within your own network.
What is port 443 normally used for?

Any web search you make, your computer connects with a server that hosts that information and fetches it for you. This connection is made via a port – either HTTPS or HTTP port.
Is it safe to open port 445?
The best approach is to explicitly block all inbound access to TCP 445 at the top of the rule base to avoid mistakenly opening it up by lower rules. We also recommend blocking port 445 on internal firewalls to segment your network – this will prevent internal spreading of the ransomware.
How do I check if port 139 is open?
For test the port 139, please try use the IP address of the server, NetBIOS or FQDN. You can use the telnet command or PortQuery tools.
How do I check my ports?
Open the Start menu, type “Command Prompt ” and select Run as administrator. Now, type “netstat -ab” and hit Enter. Wait for the results to load, port names will be listed next to the local IP address. Just look for the port number you need, and if it says LISTENING in the State column, it means your port is open.
How do I know if port 443 is open?
You can test whether the port is open by attempting to open an HTTPS connection to the computer using its domain name or IP address. To do this, you type https://www.example.com in your web browser’s URL bar, using the actual domain name of the server, or https://192.0.2.1, using the server’s actual numeric IP address.
