Many services depend on the RPC service to start successfully. By default, this service is turned off. The Remote Storage Notification system service notifies users when they read from or write to files that are available only from a secondary storage media.
Stopping this service prevents this notification. The Remote Storage system service stores infrequently used files on a secondary storage medium. If you stop this service, users cannot move or retrieve files from the secondary storage media. Although the Routing and Remote Access service can use all the following protocols, the service typically uses only a few of them. For example, if you configure a VPN gateway that is behind a filtering router, you will probably use only one protocol.
For more information about this, see the References section. The Server system service provides RPC support and file sharing, print sharing, and named pipe sharing over the network.
The Server service lets users share local resources, such as disks and printers, so that other users on the network can access them. It also enables named pipe communication between programs that are running on the local computer and on other computers. Named pipe communication is memory that is reserved for the output of one process to be used as input for another process. The input-accepting process does not have to be local to the computer.
Preloaded Lmhosts entries will bypass the DNS resolver. Windows and newer clients can work over port The SharePoint Portal Server system service lets you develop an intelligent portal that seamlessly connects users, teams, and knowledge. It helps people take advantage of relevant information across business processes.
Microsoft SharePoint Portal Server provides an enterprise business solution that integrates information from various systems into one solution through single sign-on and enterprise application integration capabilities. It accepts and queues email messages for remote destinations, and it retries at set intervals.
Windows domain controllers use the SMTP service for intersite e-mail-based replication. SNMP Service includes agents that monitor activity in network devices and report to the network console workstation.
SNMP Service provides a method of managing network hosts such as workstation or server computers, routers, bridges, and hubs from a centrally located computer that is running network management software.
SNMP performs management services by using a distributed architecture of management systems and agents. These messages are sent to a trap destination. For example, an agent can be configured to start an authentication trap if an unrecognized management system sends a request for information.
The trap destination must be a network-enabled host that is running SNMP management software. SSDP Discovery Service manages receipt of device presence announcements, updates its cache, and sends these notifications to clients that have outstanding search requests.
The registered event callbacks are then turned into subscription requests. SSDP Discovery Service then monitors for event notifications and sends these requests to the registered callbacks. This system service also provides periodic announcements to hosted devices. A Telnet server supports two kinds of authentication and supports the following kinds of terminals:.
Terminal Services provides a multi-session environment that enables client devices to access a virtual Windows desktop session and Windows-based programs that are running on the server. Terminal Services enables multiple users to be connected interactively to a computer. The Terminal Services Licensing system service installs a license server and provides licenses to registered clients when the clients connect to a terminal server a server that has Terminal Server enabled.
Terminal Services Licensing is a low-impact service that stores the client licenses that are issued for a terminal server and tracks the licenses that are issued to client computers or terminals. The Terminal Services Session Directory system service enables clusters of load-balanced terminal servers to correctly route a user's connection request to the server where the user already has a session running.
Users are routed to the first-available terminal server regardless of whether they are running another session in the server cluster. You can use this service together with a cluster of terminal servers to increase the performance of a single terminal server by distributing sessions across multiple servers. Terminal Services Session Directory keeps track of disconnected sessions on the cluster and makes sure that users are reconnected to those sessions. Therefore, when you enable this port, the TFTP service receives incoming TFTP requests, but it does not let the selected server respond to those requests.
The service is free to respond to any such request from any source port, and the remote client then uses that port during the transfer.
Communication is bidirectional. If you have to enable this protocol through a firewall, you may want to open UDP port 69 incoming. You can then rely on other firewall features that dynamically let the service respond through temporary holes on any other port. The UPnP Device Host discovery system service implements all the components that are required for device registration, control, and the response to events for hosted devices.
The information that is registered that relates to a device, such as the description, the lifetimes, and the containers, are optionally stored to disk and are announced on the network after registration or when the operating system restarts.
The service also includes the web server that serves the device in addition to service descriptions and a presentation page. WINS servers are required unless all domains have been upgraded to the Active Directory directory service and unless all computers on the network are running Windows or later versions.
Windows Media Services in Windows Server and later versions replaces the following services that are included in Windows Media Services versions 4. Windows Media Services is now a single service that runs on Windows Server. Its core components were developed by using COM, and it has a flexible architecture that you can customize for specific programs. Windows Media Services supports a larger variety of control protocols. The Windows Time system service maintains date and time synchronization on all the computers on a network that are running Windows XP or later versions and Windows Server or later versions.
This service uses Network Time Protocol NTP to synchronize computer clocks so that an accurate clock value, or time stamp, is assigned for network validation and for resource access requests. The implementation of NTP and the integration of time providers help make Windows Time a reliable and scalable time service for your business.
For computers that are not joined to a domain, you can configure Windows Time to synchronize time with an external time source. If this service is turned off, the time setting for local computers is not synchronized with a time service in the Windows domain or with an externally configured time service. Windows Server uses NTP. When the Windows Time service uses a Windows domain configuration, the service requires domain controller location and authentication services.
Therefore, the ports for Kerberos and DNS are required. This option lets you open the command prompt with admin rights. In the elevated command prompt window, execute the below command. You can copy the command and paste it in the command prompt window by right-clicking inside it. In the resulting output, you will see the port number right next to the IP address ex: You can see the highlighted portion in the below image for better representation.
Keep in mind that the list will not be refreshed automatically. You have to execute the command again when you need an updated list. If you want the used port list to be updated automatically, use the below two methods.
