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.

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. You view reports in Event Viewer. The Event Log service writes events that are sent to log files by programs, by services, and by the operating system. The events contain diagnostic information in addition to errors that are specific to the source program, the service, or the component.

This service has the same firewall requirements as the File and Printer Sharing feature. Fax Service lets users use either a local fax device or a shared network fax device to send and receive faxes from their desktop programs. The File Replication service FRS is a file-based replication engine that automatically copies updates to files and folders between computers that are participating in a common FRS replica set. FRS is the default replication engine that is used to replicate the contents of the SYSVOL folder between Windows based domain controllers and Windows Server based domain controllers that are located in a common domain.

By default, the FTP control port is The default data that is used for active mode FTP port is automatically set to one port less than the control port.

Therefore, if you configure the control port to port , the default data port is port This means that the client first connects to the FTP server by using the control port. Then, the client opens a second connection to the FTP server for transferring data.

You can configure the range of high ports by using the IIS metabase. If any one of these protocols is unavailable or blocked between the client and a relevant domain controller, Group Policy will not apply or update.

For a cross-domain logon, where a computer is in one domain and the user account is in another domain, these protocols may be required for the client, the resource domain, and the account domain to communicate. ICMP is used for slow link detection. When you initiate remote group policy results reporting from a Windows Server computer, access to the destination computer’s event log is required.

See the Event Log section in this article for port requirements. Windows Server support the initiation of remote group policy update against Windows Server computers. SSL is an open standard for establishing an encrypted communications channel to help prevent the interception of extremely important information, such as credit card numbers.

Although this service works on other Internet services, it is primarily used to enable encrypted electronic financial transactions on the World Wide Web WWW.

Internet Authentication Service IAS performs centralized authentication, authorization, auditing, and accounting of users who are connecting to a network. These users can be on a LAN connection or on a remote connection. This system service provides NAT, addressing, and name resolution services for all computers on your home network or your small-office network.

When the Internet Connection Sharing feature is enabled, your computer becomes an Internet gateway on the network. Other client computers can then share one connection to the Internet, such as a dial-up connection or a broadband connection.

They do not provide these services on the external network interface. When you use the Kerberos Key Distribution Center KDC system service, users can sign in to the network by using the Kerberos version 5 authentication protocol. As in other implementations of the Kerberos protocol, the KDC is a single process that provides two services: the Authentication Service and the Ticket-Granting Service.

The Authentication Service issues ticket granting tickets, and the Ticket-Granting Service issues tickets for connection to computers in its own domain. The License Logging system service is a tool that was originally designed to help customers manage licenses for Microsoft server products that are licensed in the server client access license CAL model.

By default, the License Logging service is disabled in Windows Server Because of legacy design constraints and evolving license terms and conditions, License Logging may not provide an accurate view of the total number of CALs that are purchased compared to the total number of CALs that are used on a particular server or across the enterprise.

License Logging is not included in Windows Server and later operating systems. We recommend that only users of the Microsoft Small Business Server family of operating systems enable this service on their servers. The Message Queuing system service is a messaging infrastructure and development tool for creating distributed messaging programs for Windows. These programs can communicate across heterogeneous networks and can send messages between computers that may be temporarily unable to connect to one another.

Message Queuing helps provide security, efficient routing, support for sending messages within transactions, priority-based messaging, and guaranteed message delivery. The Microsoft POP3 service provides email transfer and retrieval services. Administrators can use this service to store and manage email accounts on the mail server. When you install POP3 service on the mail server, users can connect to the mail server and can retrieve email messages by using an email client that supports the POP3 protocol, such as Microsoft Outlook.

The Net Logon system service maintains a security channel between your computer and the domain controller to authenticate users and services. It passes the user’s credentials to a domain controller and returns the domain security identifiers and the user rights for the user. This is typically known as pass-through authentication. Net Logon is configured to start automatically only when a member computer or domain controller is joined to a domain.

Clients can use a news client, such as Microsoft Outlook Express, to retrieve newsgroups from the server and to read the headers or the bodies of the articles in each newsgroup. Offline Files and Roaming User Profiles cache user data to computers for offline use. These capabilities exist in all supported Microsoft operating systems. All of these systems use SMB. Folder Redirection redirects user data from the local computer to a remote file share, using SMB.

Primary Computer provides a capability to prevent data caching to computers that are not authorized by administrators for specific users. This system was added in Windows Server The Performance Logs and Alerts system service collects performance data from local or remote computers based on preconfigured schedule parameters and then writes that data to a log or triggers a message.

Based on the information that is contained in the named log collection setting, the Performance Logs and Alerts service starts and stops each named performance data collection. This service runs only if at least one performance data collection is scheduled. The Print Spooler system service manages all local and network print queues and controls all print jobs.

Print Spooler is the center of the Windows printing subsystem. The Remote Procedure Call RPC system service is an interprocess communication IPC mechanism that enables data exchange and invocation of functionality that is located in a different process. 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.

This does not cover Windows 7 or Office Download the Extended Security Updates datasheet. Learn more about lifecycle support deadlines. On Azure: Customers who migrate workloads to Azure will have access to Extended Security Updates for both SQL Server and Windows Server and R2 for three years after the End of Support dates for no additional charge above the cost of running the virtual machine. On-premises: Eligible customers will be able to purchase Extended Security Updates for their on-premises environment.

Customers who require outside Azure where Extended Security Updates are available at no additional charge can onboard on Year 2 of Extended Security Updates. However, if an organization did not purchase the first year of Extended Security Updates coverage, they will need to purchase both Year 1 and Year 2 Extended Security Updates.

Similarly, if an organization onboards only on Year 3, they will need to purchase all three years of Extended Security Updates. Software Assurance or an equivalent Server Subscription is required for customers to purchase Extended Security Updates on-premises. No, there are no changes to the type of updates in Extended Security Updates. Extended Security Updates do not include new features, customer-requested non-security hotfixes, or design change requests. However, Microsoft may include non-security fixes as deemed necessary.

No, there are no changes to technical support options for Extended Security Updates customers in Alternatively, if hosting on Azure, customers can use an Azure Support plan to get technical support. For those customers who need more time to upgrade and modernize their Windows Server and SQL Server and R2 on Azure, we will now provide one additional year of free extended security updates only on Azure.

We recommend upgrading to the latest versions of our software to continue to get regular security updates, either in Azure or on-premises. However, for customers that are not able to transition to a supported version before the End of Support date, we have options to help protect data and applications during the End of Support transition:. For many customers, this is an easy first step before upgrading or modernizing with newer versions or services in Azure.

Those that decide to move to Azure SQL Managed Instance PaaS will also have access to continuous security updates, as this is a fully managed solution. These customers will also have access to Extended Security Updates on Azure for no additional charges above the cost of running the virtual machine. Extended Security Updates for on-premises or hosted environments: Extended Security Updates will also be available for workloads running on-premises or in a hosting environment such as with another cloud provider.

Product licenses and Software Assurance do not need to reside on the same enrollment. Customers can purchase Extended Security Updates only for the servers they need to cover. Extended Security Updates can be purchased directly from Microsoft or a Microsoft licensing partner. In Azure: Customers can begin migrating workloads to Azure Virtual Machines immediately and apply regular security updates until the End of Support date.

You don’t need to configure anything, and there’s no additional charge for using Extended Security Updates with Azure Virtual Machines. Extended Security Updates are available to purchase typically 3 months prior to End of Support dates with delivery of Extended Security Updates beginning after End of Support. You can find more information about how to use Extended Security Updates here.

Extended Security Updates will be distributed if and when available. SQL Server does not ship a general monthly security update. If there are situations where new SQL Server important updates will not be provided and it is deemed critical by the customer but not by MSRC, we will work with the customer on a case-to-case basis to suggest appropriate mitigation.

Software Assurance does not need to be on the same enrollment. Pricing is available on published price lists. Contact your Microsoft partner or account team for more details. The price of Extended Security Updates acquired through Microsoft resellers is set by the reseller.

Pricing for Windows Server Extended Security Updates is based on Windows Server Standard per core pricing, based on the number of virtual cores in the hosted virtual machine, and subject to a minimum of 16 licenses per instance.

Pricing for SQL Server Extended Security Updates is based on SQL Server per core pricing, based on the number of virtual cores in the hosted virtual machine, and subject to a minimum of 4 licenses per instance. Software Assurance is not required. Contact your Microsoft reseller or account team for more details. If they licensed 8 cores for SQL Server on-premises and use Software Assurance benefits to have a secondary passive server i.

Customers can then apply updates to their production workload on-premises and the secondary passive server i. On—premises: Yes, Software Assurance is required for on-premises workloads. Azure Hybrid Benefit—hybrid cloud Microsoft Azure. However, they can move their workloads to Azure and get the Extended Security Updates for no additional charges above the cost of using the Azure service. Customers with Software Assurance through other enrollments e.

Pricing for Extended Security Updates will follow the current license model for the server. For example, Windows Server is licensed by core and is required for all physical cores on each server. Customers cannot buy partial periods e. EA and Extended Security Updates must overlap for at least one month at the beginning of each year of Extended Security Updates coverage. Customers must have active Software Assurance coverage or subscription licenses for at least one month at the start of each coverage period in order to be eligible for Extended Security Updates in that period.

If customers purchase Extended Security Updates while Software Assurance is active, but Software Assurance lapses before the Extended Security Update coverage period begins, customers will not be able to receive updates. Extended Security Updates are available annually, for a fixed month period. If a customer purchases Extended Security Updates in month 10 of the month period, that customer would still need to purchase the full 12 months. Customers must have purchased coverage for year 1 of Extended Security Updates in order to buy year 2, and coverage in year 2 in order to buy year 3.

Customers may buy coverage for previous years at the same time they buy coverage for a current period. It is not necessary to buy a certain period of coverage within that coverage period. Premier Support is not a base requirement, but an additional support contract is recommended if technical support will be required. Core licenses are sold in packs of two a 2-pack of Core Licenses , and packs of 16 a pack of Core Licenses.

Each processor needs to be licensed with a minimum of eight cores four 2-pack Core Licenses. Each physical server, including single-processor servers, will need to be licensed with a minimum of 16 Core Licenses eight 2-pack of Core Licenses or one pack of Core Licenses.

Additional cores can then be licensed in increments of two cores one 2-pack of Core Licenses for servers with core densities higher than 8. Customers cannot license individual Windows Server virtual machines. They must license the full physical server.

Licensing requirements for Extended Security Updates on-premises align to the licensing requirements for the underlying Software Assurance coverage or subscription. Customers will only need to know their Windows Server license position for a given server, to know how many Extended Security Update licenses they need. Customers who have covered all the underlying cores of the physical server with Windows Server Datacenter licenses should buy Extended Security Updates for the number of physical cores, irrespective of the number of VMs running on that physical server.

Customers who have covered all the underlying cores of the physical server with Windows Server Standard licenses should buy Extended Security Updates for the number of physical cores, but will only be licensed to run and update two virtual machines on the server.

Customers who wish to run and update more than two virtual machines on a server licensed with Windows Server Standard must re-license all of the physical cores on the server with both Windows Server Standard and Extended Security Updates for each additional pair of virtual machines. Microsoft will only produce updates which can be applied on the latest Service Pack. For customers who do not have Software Assurance, the alternative option to get access to Extended Security Updates is to migrate to Azure.

For variable workloads, we recommend that customers migrate on Azure via Pay-As-You-Go, which allows for scaling up or down at any time. For predictable workloads, we recommend that customers migrate to Azure via Server Subscription and Reserved Instances. Licenses and Software Assurance do not need to be on the same agreement. However, we recommend customers complete migration before the End of Support date so that they do not miss any Extended Security Updates.

If customers miss a year of Extended Security Updates coverage, they may buy coverage for previous years at the same time they buy coverage for a current period. Yes, customers can start a new , R2, , or R2 instance on Azure and have access to Extended Security Updates. Customers who purchase Extended Security Updates for production servers may also apply those security updates to servers licensed under Visual Studio MSDN subscriptions at no additional cost.

There is no limit to the number of MSDN servers a customer can cover. Premium Assurance is no longer available, but we will honor the terms of Premium Assurance for customers who already purchased it.

Software Assurance is required as a pre-requisite to Extended Security Updates. Extended Security Updates coverage is not required to be co-terminus with Software Assurance coverage, but customers must have at least one month of qualifying Software Assurance coverage remaining at the time a given year of Extended Security Updates coverage is purchased.

If they migrate to Azure, however, they can get support using their Azure Support Plan. When customers have purchased Extended Security Updates and have an existing support plan:. Scenario: Support Team will work to troubleshoot customer issue Response: Yes. Scenario: Support Team will do a root cause analysis Response: No. This program covers only the named product and the components that shipped with it.

Unless explicitly stated the scope of this program does not extend to any other products or tools that the customer may be running on or with the covered product. No, customers must purchase Extended Security Updates separately.

The cost of Extended Security Updates is not included in the price calculation of the Unified Support agreement. However, customers with Unified Support and Extended Security Updates can request technical support for the , R2, , or R2 servers covered by Extended Security Updates. Onsite or proactive support will only be available to a customer if it is part of their Unified Support agreement.

Yes, organizations which have purchased Extended Security Updates can submit support incidents using any Microsoft Support offering, including Unified and Premier Support.

Microsoft Partners are also able to submit tickets on behalf of their customers as long as the customer has purchased Extended Security Updates, though Partners will need a support agreement in place to do so.

All customers must call Microsoft Support in order to place a request for a technical support incident. As we continue to work to fully automate the validation process, the tech routers will validate whether a customer purchased Extended Security Updates. Once the customer is validated, a case will be created and routed to the appropriate queue for technical support.

Customers should provide their Enterprise Agreement number or full customer name for validation. If an investigation determines that resolution requires product enhancement available in a recent release, then a request will be made to the customer to upgrade to a more recent release where the capability is already available.

See online servicing for more details.
