In NBT, the session service runs on TCP port 139. The session service primitives offered by NetBIOS are: Call – opens a session to a remote NetBIOS name. Listen – listen for attempts to open a session to a NetBIOS name. Hang Up – close a session. Send – sends a packet to the computer on the other end of a session.
The Name Service, according to RFCs 1001 and 1002, is called NetBIOS Naming Service or NBNS. Microsoft WINS is an implementation of NBNS. It is worth saying that due to constant development of the way in which the Name Service handles conflict or merges, "group names" varies from vendor to vendor and can even be different by version e.g. with ...
Microsoft EPMAP (End Point Mapper), also known as DCE/RPC Locator service, [71] used to remotely manage services including DHCP server, DNS server and WINS. Also used by DCOM: 137: Yes: NetBIOS Name Service, used for name registration and resolution [72] [73] 138: Assigned: Yes: NetBIOS Datagram Service [11] [72] [73] 139: Yes: Assigned ...
NetBIOS Frames (NBF) is a non-routable network-and transport-level data protocol most commonly used as one of the layers of Microsoft Windows networking in the 1990s. NBF or NetBIOS over IEEE 802.2 LLC is used by a number of network operating systems released in the 1990s, such as LAN Manager, LAN Server, Windows for Workgroups, Windows 95 and Windows NT.
SMB originally operated on NetBIOS over IEEE 802.2 - NetBIOS Frames or NBF - and over IPX/SPX, and later on NetBIOS over TCP/IP (NetBT), but Microsoft has since deprecated these protocols. On NetBT, the server component uses three TCP or UDP ports: 137 (NETBIOS Name Service), 138 (NETBIOS Datagram Service), and 139 (NETBIOS Session Service).
In computer security, WinNuke is an example of a Nuke remote denial-of-service attack (DoS) that affected the Microsoft Windows 95, Microsoft Windows NT, Microsoft Windows 3.1x computer operating systems and Windows 7.
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
Use of either NetBIOS or LLMNR services on Windows is essentially automatic, since using standard DNS client APIs will result in the use of either NetBIOS or LLMNR depending on what name is being resolved (whether the name is a local name or not), the network configuration in effect (e.g. DNS suffixes in effect) and (in corporate networks) the ...
