Nov 02, 2017 · Port numbers 0 to 1024 are reserved for privileged services and designated as well-known ports. This list of port numbers are specified in RFC 1700. In TCP/IP and UDP networks, a port is an endpoint to a logical connection and the way a client program specifies a specific server program on a computer in a network.
Feb 17, 2019 · Meaning that even though SMB1 isn't actually needed for discovery or sharing (NetBIOS discovery is a completely different protocol and SMB2+3 have separate services), the NetBIOS discovery services are * still * internally dependent on that service as at 2019; they won't work unless the SMB1 service (and some others) are also enabled and fully May 22, 2018 · I just deployed AADDS and noticed that the pre-Windows 2000 domain name is AD. Is that always the default or can the name be specified during AADDS deployment? · There is no In System Configuration please go to Services tab and locate TCP/IP NetBIOS Helper service. Uncheck the box to prevent this service to start and then press OK to finish. Any change make in System Configuration will be apply after restart. But with Windows 2000 and beyond, Microsoft has moved their NetBIOS services over to port 445 — and, perhaps not surprisingly, created an entire next-generation of even more serious security problems with that port. See the port 445 page for details. RFC's The NetBIOS over IP protocols are described in a pair of consecutive Internet RFC
A Microsoft-created protocol that enables NetBIOS naming information to be transported over TCP/IP networks. The result is that Microsoft naming services can operate on a TCP/IP networking without the need for DNS services. Uses TCP ports 137 and 139, and UDP ports 137 and 138.
NetBIOS is an API providing various networking services. However, the formerly used Ethernet based networking protocol (often called NetBEUI or NBF for NetBEUI Framing) is/was often called NetBIOS too, leading to a lot of confusion. One of the major misconception about NetBIOS is the fact that people think that it has to be there in order for you to have a file share to serve files to your network users. That is actually not the case. File sharing on your LAN. NetBIOS uses these ports: UDP 137: NetBIOS name service; UDP 138: NetBIOS datagram service; TCP 139: NetBIOS NetBIOS stands for Network Basic Input/Output System, is a specification created by IBM and Microsoft that allows distributed applications to access each other’s network services independent of the transport protocol used. If you're unsure what your domain's DNS or NetBIOS name is, do the following: On a Windows server with Active Directory Domain Services or Remote Server Administration Tools installed, open your Start menu and select Run. In the input box, type dsa.msc and hit OK.
NetBIOS (Network Basic Input/Output System) was created in the early 1980's, but is surprisingly still alive and well on many networks today. Microsoft Windows still uses it for its name resolution function (often by default), when DNS is not available. Network resiliency and access to resources is a good thing, but keeping NetBIOS enabled
The NetBIOS name table is the list of NetBIOS names that corresponds to NetBIOS applications running on that computer. /A
