Azure SQL Data Warehouse Parallel Data Warehouse For content related to previous versions of SQL Server, see Configure the Windows Firewall to Allow SQL Server Access. Firewall systems help prevent unauthorized access to computer resources. If a firewall is turned on but not correctly configured, attempts to connect to SQL Server might be blocked. To access an instance of the SQL Server through a firewall, you must configure the firewall on the computer that is running SQL Server. The firewall is a component of Microsoft Windows. You can also install a firewall from another company. This topic discusses how to configure the Windows firewall, but the basic principles apply to other firewall programs. Note This topic provides an overview of firewall configuration and summarizes information of interest to a SQL Server administrator.

For more information about the firewall and for authoritative firewall information, see the firewall documentation, such as Windows Firewall with Advanced Security and IPsec. Users familiar with the Windows Firewall item in Control Panel and with the Windows Firewall with Advanced Security Microsoft Management Console MMC snap in and who know which firewall settings they want to configure can move directly to the topics in the following list Basic Firewall Information Firewalls work by inspecting incoming packets, and comparing them against a set of rules. Disable Port 445 Windows 2008 Support' title='Disable Port 445 Windows 2008 Support' />Windows supports file and printer sharing traffic by using the Server Message Block SMB protocol directly hosted on TCP. This differs from earlier. If the rules allow the packet, the firewall passes the packet to the TCPIP protocol for additional processing. If the rules do not allow the packet, the firewall discards the packet and, if logging is enabled, creates an entry in the firewall logging file. The list of allowed traffic is populated in one of the following ways When the computer that has the firewall enabled initiates communication, the firewall creates an entry in the list so that the response is allowed. The incoming response is considered solicited traffic and you do not have to configure this. An administrator configures exceptions to the firewall. This allows either access to specified programs running on your computer, or access to specified connection ports on your computer. In this case, the computer accepts unsolicited incoming traffic when acting as a server, a listener, or a peer. This is the type of configuration that must be completed to connect to SQL Server. Choosing a firewall strategy is more complex than just deciding if a given port should be open or closed. When designing a firewall strategy for your enterprise, make sure that you consider all the rules and configuration options available to you. This topic does not review all the possible firewall options. We recommend that you review the following documents Windows Firewall with Advanced Security Getting Started Guide. Windows Firewall with Advanced Security Design Guide. Introduction to Server and Domain Isolation Default Firewall Settings The first step in planning your firewall configuration is to determine the current status of the firewall for your operating system. If the operating system was upgraded from a previous version, the earlier firewall settings may have been preserved. Also, the firewall settings could have been changed by another administrator or by a Group Policy in your domain. Note Turning on the firewall will affect other programs that access this computer, such as file and print sharing, and remote desktop connections. Administrators should consider all applications that are running on the computer before adjusting the firewall settings. Programs to Configure the Firewall. Configure the Windows Firewall settings with either Microsoft Management Console or netsh. Microsoft Management Console MMC The Windows Firewall with Advanced Security MMC snap in lets you configure more advanced firewall settings. This snap in presents most of the firewall options in an easy to use manner, and presents all firewall profiles. For more information, see Using the Windows Firewall with Advanced Security Snap in later in this topic. The netsh. exe tool can be used by an administrator to configure and monitor Windows based computers at a command prompt or using a batch file. By using the netsh tool, you can direct the context commands you enter to the appropriate helper, and the helper then performs the command. Google Sketchup User Guide. A helper is a Dynamic Link Library. All operating systems that support SQL Server have a firewall helper. Windows Server 2. The details of using netsh are not discussed in this topic. However, many of the configuration options described can be configured by using netsh. For example, run the following script at a command prompt to open TCP port 1. TCP port 1. 43. SQLPort mode ENABLE scope SUBNET profile CURRENT. A similar example using the Windows Firewall for Advanced Security helper netsh advfirewall firewall add rule name SQLPort dir in protocol tcp action allow localport 1. DOMAIN. For more information about netsh, see the following links Ports Used By SQL Server The following tables can help you identify the ports being used by SQL Server. Ports Used By the Database Engine The following table lists the ports that are frequently used by the Database Engine. Scenario. Port. Comments SQL Server default instance running over TCPTCP port 1. This is the most common port allowed through the firewall. It applies to routine connections to the default installation of the Database Engine, or a named instance that is the only instance running on the computer. Named instances have special considerations. See Dynamic Ports later in this topic. SQL Server named instances in the default configuration. The TCP port is a dynamic port determined at the time the Database Engine starts. See the discussion below in the section Dynamic Ports. UDP port 1. 43. 4 might be required for the SQL Server Browser Service when you are using named instances. SQL Server named instances when they are configured to use a fixed port. The port number configured by the administrator. See the discussion below in the section Dynamic Ports. Dedicated Admin Connection. TCP port 1. 43. 4 for the default instance. Other ports are used for named instances. Check the error log for the port number. By default, remote connections to the Dedicated Administrator Connection DAC are not enabled. To enable remote DAC, use the Surface Area Configuration facet. For more information, see Surface Area Configuration. SQL Server Browser service. UDP port 1. 43. 4The SQL Server Browser service listens for incoming connections to a named instance and provides the client the TCP port number that corresponds to that named instance. Normally the SQL Server Browser service is started whenever named instances of the Database Engine are used. The SQL Server Browser service does not have to be started if the client is configured to connect to the specific port of the named instance. SQL Server instance running over an HTTP endpoint. Can be specified when an HTTP endpoint is created. The default is TCP port 8. CLEARPORT traffic and 4. SSLPORT traffic. Used for an HTTP connection through a URL. SQL Server default instance running over an HTTPS endpoint. TCP port 4. 43. Used for an HTTPS connection through a URL. HTTPS is an HTTP connection that uses secure sockets layer SSL. Service Broker. TCP port 4. To verify the port used, execute the following query SELECT name, protocoldesc, port, statedesc. FROM sys. tcpendpoints. Description of the IPC share Smallvoid. The IPC is a hidden share. Server service Disabling the service will remove the share. The IPC share is used for Inter Proces Communication by using RPC Remote Procedure Call, allowing the client to send different commands to the server. List all shares. List all users. List files within a share. StopStart services. Certain commands can be accessed anonymously. NULL session depending on the configuration of the server. If the command cannot be called anonymously, then the client has to authenticate. Access is granted if the client can provide proper credentials username and password. If not able to do this, then the user at the client. IPC, The domain password you supplied is not correct. You must supply a password to make this connection Incorrect password or unknown username for. Note it is possible to access the IPC share of a server by using a different credentials. Even if needing to use a domain user. Note to block access to Remote Procedure Call RPC, then one should ensure that the firewall blocks the following network ports. TCP Port 1. 35 RPC Endpoint Mapper. UDP Port 1. 37 Netbios. UDP Port 1. 38 Netbios. TCP Port 1. 39 Netbios. TCP and UDP Port 4. Named Pipes. Note Windows 9. Me doesnt support logon with different credentials. Therefore one have to make sure the userid and password. Win. 9x machine matches one of the accounts on the Win. NT machine. This can be done by using one of the following options. Note if sure that the account is properly setup then one can configure an audit. More Info MS KB1. More Info MS KB1. More Info MS KB1.
