Direct hostedNetBIOS-lessSMB traffic uses port 445 (TCP). In this situation, a four-byte header precedes the SMB traffic. The first byte of this header is always 0x00, and the next 3 bytes are the length of the remaining data. Use the following steps to disable NetBIOS over TCP/IP. ...

To determine if NetBIOS over TCP/IP is enabled on a Windows-based computer, issue anet config redirectorornet config servercommand at a command prompt. The output shows bindings for the NetbiosSmb device (which is the "NetBIOS-less" transport) and for the NetBT_Tcpip device (which is th...
SMB协议是运行在会话层之上的网络层协议,有两种运行方式,第一种通过NetBios API,如下图: 使用的是UDP的137和138端口以及TCP的137和139的端口。 第二种是直接运行在TCP和UDP协议之上,使用的是445端口,可以称为"Direct hosting of SMB over TCP/IP"。 总结一下,Windows主机上文件打印、文件共享等都通过SMB协议来...
