Good stuff, u will be well paid one day. Thanks for VS 22 prof. Hello everyone! Does anyone have the Mysql Enterprise Edition code? Thank you. Thank you all so much!!! Much appreciated! 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.
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.

As a database server , it is a software product with the primary function of storing and retrieving data as requested by other software applications —which may run either on the same computer or on another computer across a network including the Internet. Microsoft markets at least a dozen different editions of Microsoft SQL Server, aimed at different audiences and for workloads ranging from small single-machine applications to large Internet-facing applications with many concurrent users.
Its name is entirely descriptive, it being server software that responds to queries in the SQL language. As of July [update] , the following versions are supported by Microsoft:. From SQL Server onward, the product is supported on x64 processors only and must have 1.
The RTM version is Microsoft makes SQL Server available in multiple editions, with different feature sets and targeting different users. These editions are: [8] [9]. The protocol layer implements the external interface to SQL Server. TDS is an application layer protocol, used to transfer data between a database server and a client.
Initially designed and developed by Sybase Inc. Consequently, access to SQL Server is available over these protocols. Data storage is a database , which is a collection of tables with typed columns. SQL Server supports different data types, including primitive types such as Integer , Float , Decimal , Char including character strings , Varchar variable length character strings , binary for unstructured blobs of data , Text for textual data among others.
In addition to tables, a database can also contain other objects including views , stored procedures , indexes and constraints , along with a transaction log. A SQL Server database can contain a maximum of 2 31 objects, and can span multiple OS-level files with a maximum file size of 2 60 bytes 1 exabyte.
Secondary data files, identified with a. Log files are identified with the. Storage space allocated to a database is divided into sequentially numbered pages , each 8 KB in size.
A page is marked with a byte header which stores metadata about the page including the page number, page type, free space on the page and the ID of the object that owns it.
The page type defines the data contained in the page. This data includes: data stored in the database, an index, an allocation map, which holds information about how pages are allocated to tables and indexes; and a change map which holds information about the changes made to other pages since last backup or logging, or contain large data types such as image or text. A database object can either span all 8 pages in an extent "uniform extent" or share an extent with up to 7 more objects "mixed extent".
A row in a database table cannot span more than one page, so is limited to 8 KB in size. However, if the data exceeds 8 KB and the row contains varchar or varbinary data, the data in those columns are moved to a new page or possibly a sequence of pages, called an allocation unit and replaced with a pointer to the data.
For physical storage of a table, its rows are divided into a series of partitions numbered 1 to n. The partition size is user defined; by default all rows are in a single partition. A table is split into multiple partitions in order to spread a database over a computer cluster.
Rows in each partition are stored in either B-tree or heap structure. If the table has an associated, clustered index to allow fast retrieval of rows, the rows are stored in-order according to their index values, with a B-tree providing the index. The data is in the leaf node of the leaves, and other nodes storing the index values for the leaf data reachable from the respective nodes.
If the index is non-clustered, the rows are not sorted according to the index keys. An indexed view has the same storage structure as an indexed table. A table without a clustered index is stored in an unordered heap structure. However, the table may have non-clustered indices to allow fast retrieval of rows. In some situations the heap structure has performance advantages over the clustered structure.
Both heaps and B-trees can span multiple allocation units. Any 8 KB page can be buffered in-memory, and the set of all pages currently buffered is called the buffer cache. The amount of memory available to SQL Server decides how many pages will be cached in memory. The buffer cache is managed by the Buffer Manager. Either reading from or writing to any page copies it to the buffer cache. Subsequent reads or writes are redirected to the in-memory copy, rather than the on-disc version.
The page is updated on the disc by the Buffer Manager only if the in-memory cache has not been referenced for some time. Each page is written along with its checksum when it is written. When reading the page back, its checksum is computed again and matched with the stored version to ensure the page has not been damaged or tampered with in the meantime.
SQL Server allows multiple clients to use the same database concurrently. As such, it needs to control concurrent access to shared data, to ensure data integrity—when multiple clients update the same data, or clients attempt to read data that is in the process of being changed by another client.
SQL Server provides two modes of concurrency control: pessimistic concurrency and optimistic concurrency. When pessimistic concurrency control is being used, SQL Server controls concurrent access by using locks.
Locks can be either shared or exclusive. Exclusive lock grants the user exclusive access to the data—no other user can access the data as long as the lock is held.
Shared locks are used when some data is being read—multiple users can read from data locked with a shared lock, but not acquire an exclusive lock. The latter would have to wait for all shared locks to be released. Locks can be applied on different levels of granularity—on entire tables, pages, or even on a per-row basis on tables. For indexes, it can either be on the entire index or on index leaves. The level of granularity to be used is defined on a per-database basis by the database administrator.
While a fine-grained locking system allows more users to use the table or index simultaneously, it requires more resources, so it does not automatically yield higher performance. SQL Server also includes two more lightweight mutual exclusion solutions—latches and spinlocks—which are less robust than locks but are less resource intensive.
SQL Server also monitors all worker threads that acquire locks to ensure that they do not end up in deadlocks —in case they do, SQL Server takes remedial measures, which in many cases are to kill one of the threads entangled in a deadlock and roll back the transaction it started. The Lock Manager maintains an in-memory table that manages the database objects and locks, if any, on them along with other metadata about the lock. Access to any shared object is mediated by the lock manager, which either grants access to the resource or blocks it.
SQL Server also provides the optimistic concurrency control mechanism, which is similar to the multiversion concurrency control used in other databases. The mechanism allows a new version of a row to be created whenever the row is updated, as opposed to overwriting the row, i.
Both the old as well as the new versions of the row are stored and maintained, though the old versions are moved out of the database into a system database identified as Tempdb. When a row is in the process of being updated, any other requests are not blocked unlike locking but are executed on the older version of the row. If the other request is an update statement, it will result in two different versions of the rows—both of them will be stored by the database, identified by their respective transaction IDs.
The main mode of retrieving data from a SQL Server database is querying for it. The query declaratively specifies what is to be retrieved. It is processed by the query processor, which figures out the sequence of steps that will be necessary to retrieve the requested data. The sequence of actions necessary to execute a query is called a query plan.
There might be multiple ways to process the same query. For example, for a query that contains a join statement and a select statement, executing join on both the tables and then executing select on the results would give the same result as selecting from each table and then executing the join, but result in different execution plans.
In such case, SQL Server chooses the plan that is expected to yield the results in the shortest possible time. This is called query optimization and is performed by the query processor itself.
SQL Server includes a cost-based query optimizer which tries to optimize on the cost, in terms of the resources it will take to execute the query. Given a query, then the query optimizer looks at the database schema , the database statistics and the system load at that time. It then decides which sequence to access the tables referred in the query, which sequence to execute the operations and what access method to be used to access the tables.
For example, if the table has an associated index, whether the index should be used or not: if the index is on a column which is not unique for most of the columns low "selectivity" , it might not be worthwhile to use the index to access the data. Finally, it decides whether to execute the query concurrently or not. While a concurrent execution is more costly in terms of total processor time, because the execution is actually split to different processors might mean it will execute faster.
Once a query plan is generated for a query, it is temporarily cached. For further invocations of the same query, the cached plan is used. Unused plans are discarded after some time. SQL Server also allows stored procedures to be defined. Stored procedures are parameterized T-SQL queries, that are stored in the server itself and not issued by the client application as is the case with general queries.
Stored procedures can accept values sent by the client as input parameters, and send back results as output parameters. They can call defined functions, and other stored procedures, including the same stored procedure up to a set number of times.
They can be selectively provided access to. Unlike other queries, stored procedures have an associated name, which is used at runtime to resolve into the actual queries. Also because the code need not be sent from the client every time as it can be accessed by name , it reduces network traffic and somewhat improves performance. It exposes keywords for the operations that can be performed on SQL Server, including creating and altering database schemas, entering and editing data in the database as well as monitoring and managing the server itself.
Client applications that consume data or manage the server will leverage SQL Server functionality by sending T-SQL queries and statements which are then processed by the server and results or errors returned to the client application.
For this it exposes read-only tables from which server statistics can be read. Management functionality is exposed via system-defined stored procedures which can be invoked from T-SQL queries to perform the management operation.
Linked servers allow a single query to process operations performed on multiple servers. It natively implements support for the SQL Server features including the Tabular Data Stream implementation, support for mirrored SQL Server databases, full support for all data types supported by SQL Server, asynchronous operations, query notifications, encryption support, as well as receiving multiple result sets in a single database session.
