TCP 445: Introduced with the direct hosting of SMB over TCP/IP, this port bypasses the NetBIOS layer. Port 445 is used for direct SMB communication without the need for NetBIOS, making it the primary port for file sharing and access to remote printers and for inter-process communication amo...
Port 445 is one of several Microsoft Networking ports that are used today as well as in the older versions of Windows. They were used well with theNetBIOSservices in the older versions. Whereas in the newer versions, it is used for direct TCP/IP without the help of NetBIOS. You May Al...

Windows Server 2025 includes client access control for SMB over QUIC. SMB over QUIC is an alternative to TCP and RDMA that supplies secure connectivity to edge file servers over untrusted networks. Client access control introduces more controls to restrict access to your data by using certificates....

What Is a Port? As we all know, IP addresses are used to identify computers on a network. The TCP/IP protocol connects one IP address to another to form a network. Many services typically run on a computer, such as web services that allow users to access web pages, SSH services that...
to TCP port 445 on all Windows systems. By blocking inbound access, a system can be protected from the attack, and by blocking outbound access, affected systems can be prevented from attacking others. Windows Firewall is only able to block inbound access – which is why IPSec is required....
An SMB port is a network port commonly used for file sharing that is susceptible to an exploit known as EternalBlue exploit that resulted in WannaCry.
Server message block commonly uses transmission control protocol (TCP) ports 139 and 445 for communication. Knowing the ports is essential for configuring firewalls and ensuring that the protocol can operate smoothly within your network setup.
primarily uses tcp port 445. in some cases, it might also use ports 137, 138, and 139 if netbios over tcp/ip is enabled. these ports facilitate the communication required for file and printer sharing across networks. ensuring these ports are open and properly configured in your firewall ...
