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.

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. This service enables the Distributed Link Tracking Client service to track linked documents that are moved to a location in another NTFS file system volume in the same domain.
The Distributed Transaction Coordinator DTC system service coordinates transactions that are distributed across multiple computer systems and resource managers, such as databases, message queues, file systems, or other transaction-protected resource managers.
DNS servers are required to locate devices and services that are identified by using DNS names and to locate domain controllers in Active Directory. The Event Log system service logs event messages that are generated by programs and by the Windows operating system. Event log reports contain information that you can use to diagnose problems.
SQL Server Express - Wikipedia
Microsoft Access offers parameterized queries. These queries and Access tables can be referenced from other programs like VB6 and. Microsoft Access is a file server -based database. Unlike client—server relational database management systems RDBMS , Microsoft Access does not implement database triggers , stored procedures , or transaction logging. Access includes table-level triggers and stored procedures built into the ACE data engine. Thus a Client-server database system is not a requirement for using stored procedures or table triggers with Access Tables, queries, forms, reports and macros can now be developed specifically for web based applications in Access Integration with Microsoft SharePoint is also highly improved.
The edition of Microsoft Access introduced a mostly flat design and the ability to install apps from the Office Store, but it did not introduce new features. The theme was partially updated again for , but no dark theme was created for Access.
NET web forms can query a Microsoft Access database, retrieve records and display them on the browser. SharePoint Server via Access Services allows for Access databases to be published to SharePoint, thus enabling multiple users to interact with the database application from any standards-compliant Web browser. Access Web databases published to SharePoint Server can use standard objects such as tables, queries, forms, macros, and reports.
Access Services stores those objects in SharePoint. Access offers the ability to publish Access web solutions on SharePoint The macro language is enhanced to support more sophisticated programming logic and database level automation. Microsoft Access can also import or link directly to data stored in other applications and databases. Microsoft offers free runtime versions of Microsoft Access which allow users to run an Access desktop application without needing to purchase or install a retail version of Microsoft Access.
This actually allows Access developers to create databases that can be freely distributed to an unlimited number of end-users.
These runtime versions of Access and later can be downloaded for free from Microsoft. The runtime version allows users to view, edit and delete data, along with running queries, forms, reports, macros and VBA module code. The runtime version does not allow users to change the design of Microsoft Access tables, queries, forms, reports, macros or module code. The runtime versions are similar to their corresponding full version of Access and usually compatible with earlier versions; for example Access Runtime allows a user to run an Access application made with the version as well as through Due to deprecated features in Access , its runtime version is also unable to support those older features.
Access stores all database tables, queries, forms, reports, macros, and modules in the Access Jet database as a single file. For query development, Access offers a "Query Designer", a graphical user interface that allows users to build queries without knowledge of structured query language.
In the Query Designer, users can "show" the datasources of the query which can be tables or queries and select the fields they want returned by clicking and dragging them into the grid. One can set up joins by clicking and dragging fields in tables to fields in other tables. Access allows users to view and manipulate the SQL code if desired.
Any Access table, including linked tables from different data sources, can be used in a query. Access also supports the creation of "pass-through queries". This enables users to interact with data stored outside the Access program without using linked tables or Jet. When developing reports in "Design View" additions or changes to controls cause any linked queries to execute in the background and the designer is forced to wait for records to be returned before being able to make another change.
This feature cannot be turned off. Non-programmers can use the macro feature to automate simple tasks through a series of drop-down selections. Macros allow users to easily chain commands together such as running queries, importing or exporting data, opening and closing forms, previewing and printing reports, etc.
Macros support basic logic IF-conditions and the ability to call other macros. Macros can also contain sub-macros which are similar to subroutines. In Access , enhanced macros included error-handling and support for temporary variables. Access also introduced embedded macros that are essentially properties of an object's event.
This eliminated the need to store macros as individual objects. However, macros were limited in their functionality by a lack of programming loops and advanced coding logic until Access With significant further enhancements introduced in Access , the capabilities of macros became fully comparable to VBA. They made feature rich web-based application deployments practical, via a greatly enhanced Microsoft SharePoint interface and tools, as well as on traditional Windows desktops.
It is similar to Visual Basic 6. To create a richer, more efficient and maintainable finished product with good error handling, most professional Access applications are developed using the VBA programming language rather than macros, except where web deployment is a business requirement.
In the database container or navigation pane in Access and later versions, the system automatically categorizes each object by type e.
Many Access developers use the Leszynski naming convention , though this is not universal; it is a programming convention, not a DBMS-enforced rule. Developers deploy Microsoft Access most often for individual and workgroup projects the Access 97 speed characterization was done for 32 users.
Databases under 1 GB in size which can now fit entirely in RAM and simultaneous users are well within the capabilities of Microsoft Access.
Disk-intensive work such as complex searching and querying take the most time. As data from a Microsoft Access database can be cached in RAM, processing speed may substantially improve when there is only a single user or if the data is not changing.
In the past, the effect of packet latency on the record-locking system caused Access databases to run slowly on a virtual private network VPN or a wide area network WAN against a Jet database. As of , [update] broadband connections have mitigated this issue. Performance can also be enhanced if a continuous connection is maintained to the back-end database throughout the session rather than opening and closing it for each table access.
In July , Microsoft acknowledged an intermittent query performance problem with all versions of Access and Windows 7 and Windows Server R2 due to the nature of resource management being vastly different in newer operating systems. In earlier versions of Microsoft Access, the ability to distribute applications required the purchase of the Developer Toolkit; in Access , and Access the "Runtime Only" version is offered as a free download, [44] making the distribution of royalty-free applications possible on Windows XP, Vista, 7 and Windows 8.
Microsoft Access applications can adopt a split-database architecture. The single database can be divided into a separate "back-end" file that contains the data tables shared on a file server and a "front-end" containing the application's objects such as queries, forms, reports, macros, and modules. The "front-end" Access application is distributed to each user's desktop and linked to the shared database. Using this approach, each user has a copy of Microsoft Access or the runtime version installed on their machine along with their application database.
This reduces network traffic since the application is not retrieved for each use. The "front-end" database can still contain local tables for storing a user's settings or temporary data.
This split-database design also allows development of the application independent of the data. One disadvantage is that users may make various changes to their own local copy of the application and this makes it hard to manage version control. When a new version is ready, the front-end database is replaced without impacting the data database.
Microsoft Access has two built-in utilities, Database Splitter [46] and Linked Table Manager, to facilitate this architecture. Linked tables in Access use absolute paths rather than relative paths, so the development environment either has to have the same path as the production environment or a "dynamic-linker" routine can be written in VBA.
For very large Access databases, this may have performance issues and a SQL backend should be considered in these circumstances. To scale Access applications to enterprise or web solutions, one possible technique involves migrating to Microsoft SQL Server or equivalent server database. A client—server design significantly reduces maintenance and increases security, availability, stability, and transaction logging.
This feature was removed from Access A variety of upgrading options are available. The corresponding SQL Server data type is binary, with only two states, permissible values, zero and 1. Regardless, SQL Server is still the easiest migration. Retrieving data from linked tables is optimized to just the records needed, but this scenario may operate less efficiently than what would otherwise be optimal for SQL Server. For example, in instances where multi-table joins still require copying the whole table across the network.
The views and stored procedures can significantly reduce the network traffic for multi-table joins. Finally, some Access databases are completely replaced by another technology such as ASP.
NET or Java once the data is converted. Further, Access application procedures, whether VBA and macros, are written at a relatively higher level versus the currently available alternatives that are both robust and comprehensive. Note that the Access macro language, allowing an even higher level of abstraction than VBA, was significantly enhanced in Access and again in Access In many cases, developers build direct web-to-data interfaces using ASP. NET, while keeping major business automation processes, administrative and reporting functions that don't need to be distributed to everyone in Access for information workers to maintain.
Microsoft Access applications can be made secure by various methods, the most basic being password access control; this is a relatively weak form of protection. A higher level of protection is the use of workgroup security requiring a user name and password. Users and groups can be specified along with their rights at the object type or individual object level. 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. World Wide Web Publishing Service provides the infrastructure that you must have to register, manage, monitor, and serve websites and programs that are registered with IIS.
This system service contains a process manager and a configuration manager. The process manager controls the processes where custom applications and websites reside.
The configuration manager reads the stored system configuration for World Wide Web Publishing Service and makes sure that Http. The following table summarizes the information from the System services ports section. This table is sorted by port number instead of by service name. Port is only used on a Windows Server domain controller or a Windows Server R2 domain controller; it is not used on a Windows Server domain controller.
Port is used by DFSR only when creating a new empty replicated folder. Microsoft provides part of the information that is in this table in a Microsoft Excel worksheet. This worksheet is available for download from the Microsoft Download Center. Application servers, client computers, and domain controllers that are located in common or external forests have service dependencies so that user-initiated and computer-initiated operations such as domain join, logon authentication, remote administration, and Active Directory replication work correctly.
Such services and operations require network connectivity over specific port and networking protocols. A summarized list of services, ports, and protocols required for member computers and domain controllers to inter-operate with one another or for application servers to access Active Directory include but are not limited to the following.
