Don't use the port information in this article to configure Windows Firewall. The Windows Server system includes a comprehensive and integrated infrastructure to meet the requirements of developers and information technology IT professionals.
This system runs programs and solutions that you can use to obtain, analyze, and share information quickly and easily. These Microsoft client, server, and server program products use different network ports and protocols to communicate with client systems and with other server systems over the network.
Dedicated firewalls, host-based firewalls, and Internet Protocol security IPsec filters are other important components that you must have to help secure your network.
However, if these technologies are configured to block ports and protocols that are used by a specific server, that server will no longer respond to client requests. The System services ports section:.
The Ports and protocols section includes a table that summarizes the information from the System services ports section. The table is sorted by the port number instead of by the service name. Use this section to quickly determine which services listen on a particular port. This article uses certain terms in specific ways. To help avoid confusion, make sure that you understand how the article uses these terms:. This article doesn't specify which services rely on other services for network communication.
A full discussion of the architecture of the Windows operating systems is beyond the scope of this article. Although many services may rely on a particular TCP or UDP port, only one service or process at a time can listen on that port. These ports are also informally known as random RPC ports. In these cases, RPC clients rely on the RPC endpoint mapper to tell them which dynamic port or ports were assigned to the server.
You can also restrict the range of ports that RPC dynamically assigns to a small range, regardless of the service. For more information about this topic, see the References section. This article includes information about the system services roles and the server roles for the Microsoft products that are listed in the Applies to section. Although this information may also apply to Windows XP and to Microsoft Windows Professional, this article is focused on server-class operating systems.
Therefore, this article describes the ports that a service listens on instead of the ports that client programs use to connect to a remote system. This section provides a description of each system service, includes the logical name that corresponds to the system service, and displays the ports and the protocols that each service requires. Active Directory runs under the Lsass. Domain controllers, client computers, and application servers require network connectivity to Active Directory over specific hard-coded ports.
Additionally, unless a tunneling protocol is used to encapsulate traffic to Active Directory, a range of ephemeral TCP ports between to and to are required. If your computer network environment uses only Windows Server R2, Windows Server , Windows 7, or Windows Vista, you must enable connectivity over the high port range of through If your computer network environment uses Windows Server R2, Windows Server , Windows 7, or Windows Vista together with versions of Windows earlier than Windows Server and Windows Vista, you must enable connectivity over both port ranges: High port range of through Low port range of through If your computer network environment uses only versions of Windows earlier than Windows Server and Windows Vista, you must enable connectivity over the low port range of through In this encapsulated scenario, you must allow the following items through the router instead of opening all the ports and protocols listed in this topic:.
Finally, you can hard-code the port that is used for Active Directory replication by following the steps in Restricting Active Directory RPC traffic to a specific port.
The following settings are LDAP session options:. FTP is the only network protocol that has a plug-in that is included with Windows Server. The ALG FTP plug-in supports these sessions by redirecting all traffic that meets the following criteria to a private listening port in the range of to on the loopback adapter:.
NET out-of-process session states. NET State Service stores session data out-of-process. The service uses sockets to communicate with ASP. NET that is running on a web server. Certificate Services is part of the core operating system. By using Certificate Services, a business can act as its own certification authority CA.
It lets the business issue and manage digital certificates for programs and protocols such as:. For more information, see 3. The Cluster service controls server cluster operations and manages the cluster database. A cluster is a collection of independent computers that act as a single computer. Managers, programmers, and users see the cluster as a single system.
The software distributes data among the nodes of the cluster. If a node fails, other nodes provide the services and data that were formerly provided by the missing node. When a node is added or repaired, the cluster software migrates some data to that node. By default, DTLS is enabled. The Computer Browser system service maintains an up-to-date list of computers on your network and supplies the list to programs that request it. The Computer Browser service is used by Windows-based computers to view network domains and resources.
Computers that are designated as browsers maintain browse lists that contain all shared resources that are used on the network. Earlier versions of Windows-based programs, such as My Network Places, the net view command, and Windows Explorer, all require browsing capability. For example, when you open My Network Places on a computer that is running Microsoft Windows 95, a list of domains and computers appears. To display this list, the computer obtains a copy of the browse list from a computer that is designated as a browser.
If you are running only Windows Vista and later versions of Windows, the browser service is no longer required. You can use this service to adjust the advanced network settings of DHCP clients. The Distributed File System Replication DFSR service is a state-based, multi-master file replication engine that automatically copies updates to files and folders between computers that are participating in a common replication group. It is not used on a Windows Server domain controller.
The Distributed Link Tracking Server system service stores information so that files that are moved between volumes can be tracked to each volume in the domain. The Distributed Link Tracking Server service runs on each domain controller in a domain.
Thanks for your time, it's not quite the page I'm looking for, a page with all the functions provided in the terminal such as kill. Ill post here if i find.
I haven't found much about this as of now. Please post if you find anything. I have to downvote because of your confusion about kill. As any fool knows, in PS you use Get-Command to understand what command you're running, and it shows you that, on Windows, kill is an alias for Stop-Process. On Linux it's not an alias but the native command.

This worked for a socket that uses a particular port number in Google Cloud as well! Thanks a ton — peevesy. Even if this is a correct answer. The question was asked for windows environment and your answer is invalid on a Linux system.
Italo Borssatto Italo Borssatto I got the error: bash: taskill: command not found — Chau Giang. ChauGiang It seems a typo. Use tskill instead of taskill.
Instead, use this: netstat -tulpn grep "" Here, it will list some columns specifying the port and the PID. Then we can kill that process by typing: kill -9 pid here -9 means soft remove.

Clients when connecting to an application or service will make use of an ephemeral port from its machine to connect to a well-known port defined for that application or service.
In a scenario where the same browser is creating a lot of connections to multiple website, for any new connection that the browser is attempting, an ephemeral port is used. After some time, you will notice that the connections will start to fail and one high possibility for this would be because the browser has used all the available ports to make connections outside and any new attempt to establish a connection will fail as there are no more ports available.
When all the ports are on a machine are used, we term it as port exhaustion. The new default start port is , and the new default end port is This is a change from the configuration of earlier versions of Windows that used a default port range of through The port range is now a range that has a starting point and an ending point.
Microsoft customers who deploy servers that are running Windows Server may have problems that affect RPC communication between servers if firewalls are used on the internal network. In these situations, we recommend that you reconfigure the firewalls to allow traffic between servers in the dynamic port range of through This range is in addition to well-known ports that are used by services and applications.
Or, the port range that is used by the servers can be modified on each server. You adjust this range by using the netsh command, as follows. The above command sets the dynamic port range for TCP.
The start port is number, and the total number of ports is range. The following are sample commands:. These sample commands set the dynamic port range to start at port and to end at port ports. The minimum range of ports that can be set is The minimum start port that can be set is
