Microsoft Sql Server Error 258

NoteFor other scenarios, see:.These steps are not in the order of the most likely problems which you probably already tried. These steps are in order of the most basic problems to more complex problems. These steps assume that you are connecting to SQL Server instance from another computer by using the TCP/IP protocol, which is the most common situation.These instructions are useful when troubleshooting the ' Connect to Server' error, which can be Error Number: 11001 (or 53), Severity: 20, State: 0. The following is an example of an error message:A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)(provider: TCP Provider, error: 0 - No such host is known.) (Microsoft SQL Server, Error: 11001)This error usually means that the client can't find the SQL Server instance. This normally happens when at least one of the following problems exist:.

The name of the computer hosting the SQL Server. Instance does not resolve the the correct IP. The TCP port number is not specified correctly.

For help, see.Get instance name from Configuration MangerOn the server that hosts the SQL Server instance, verify the instance name. Use.Configuration Manager is automatically installed on the computer when SQL Server is installed. Instructions on starting Configuration Manager vary slightly by version of SQL Server and Windows.

For version specific details, see.).Sign in to the computer hosting the instance of SQL Server.Start SQL Server Configuration Manager.In the left pane, select SQL Server Services.In the right pane, verify the name of the instance of the database engine. SQL SERVER (MSSQLSERVER) denotes a default instance of SQL Server. The name of the default instance is. SQL SERVER denotes a named instance of SQL Server. The name of the name instance is Verify - the instance is runningTo verify that the instance is running, in Configuration Manager look at the symbol by the SQL Server instance. A green arrow indicates that an instance is running. A red square indicates that an instance is stopped.If the instance is stopped, right-click the instance and then click Start.

The server instance starts, and the indicator becomes a green arrow. Verify - SQL Server Browser service is runningTo connect to a named instance, SQL Server Browser service must be running.

In Configuration Manager, locate SQL Server Browser service and verify that it is running. If it is not running, start it. SQL Server Browser service is not required for default instances.A default instance of SQL Server does not require SQL Server Browser service.

Testing a local connectionBefore troubleshooting a connection problem from another computer, first test your ability to connect from a client application installed locally on the computer that is running SQL Server. Connecting locally avoids issues with networks and firewalls.This procedure uses SQL Server Management Studio. If you do not have Management Studio installed, see.

If you are not able to install Management Studio, you can test the connection using the sqlcmd.exe utility. Sqlcmd.exe is installed with the Database Engine.

For information about sqlcmd.exe, see.).Sign in to the computer where SQL Server is installed, using a login that has permission to access SQL Server. (During installation, SQL Server requires at least one login to be specified as a SQL Server Administrator.

If you do not know an administrator, see.).On the Start page, type SQL Server Management Studio, or on older versions of Windows on the Start menu, point to All Programs, point to Microsoft SQL Server, and then click SQL Server Management Studio.In the Connect to Server dialog box, in the Server type box, select Database Engine. In the Authentication box, select Windows Authentication. In the Server name box, type one of the following connection types: Connecting toTypeExampleDefault instanceACCNT27Named InstanceACCNT27PAYROLL. NoteSome error messages passed to the client intentionally do not give enough information to troubleshoot the problem.

This is a security feature to avoid providing an attacker with information about SQL Server. To view the complete information about the error, look in the SQL Server error log. The details are provided there.If you receive error 18456 Login failed for user, Books Online topic contains additional information about error codes. And Aaron Bertrand's blog has a very extensive list of error codes at. You can view the error log with SSMS (if you can connect), in the Management section of the Object Explorer. Otherwise, you can view the error log with the Windows Notepad program. The default location varies with your version and can be changed during setup.

The default location for SQL Server 2019 (15.x) is C:Program FilesMicrosoft SQL ServerMSSQL15.MSSQLSERVERMSSQLLogERRORLOG.If you can connect using shared memory, test connecting using TCP. You can force a TCP connection by specifying tcp: before the name. For example: Connecting to:Type:Example:Default instancetcp:tcp:ACCNT27Named Instancetcp:tcp:ACCNT27PAYROLL.If you can connect with shared memory but not TCP, then you must fix the TCP problem.

The most likely issue is that TCP is not enabled. To enable TCP, See the steps above.If your goal is to connect with an account other than an administrator account, once you can connect as an administrator, try the connection again using the Windows Authentication login or the SQL Server Authentication login that the client application will be using.Get the IP address of the serverGet the IP Address of the computer hosting the instance of SQL Server. On the Start menu, click Run. In the Run window, type cmd, and then click OK. In the command prompt window, type ipconfig and then press enter. Make a note of the IPv4 Address and the IPv6 Address.SQL Server can connect using the either IP version 4 protocol or IP version 6 protocol.

Your network could allow either or both. Most people start by troubleshooting the IPv4 address. It's shorter and easier to type.

Get the SQL Server instance TCP portIn most cases, you connect to the Database Engine from another computer using the TCP protocol. Using SQL Server Management Studio on the computer running SQL Server, connect to the instance of SQL Server. In Object Explorer, expand Management, expand SQL Server Logs, and then double-click the current log. In the Log Viewer, click the Filter button on the toolbar.

In the Message contains text box, type server is listening on, click Apply filter, and then click OK. A message similar to Server is listening on 'any' 1433 should be listed.This message indicates that this instance of SQL Server is listening on all the IP addresses on this computer (for IP version 4) and is listening to TCP port 1433. (TCP port 1433 is usually the port used by the Database Engine or a default instance of SQL Server. Only one instance of SQL Server can use a port, so if there is more than one instance of SQL Server installed, some instances must use other port numbers.) Make a note of the port number used by the SQL Server instance that you are trying to connect to. NoteIP address 127.0.0.1 is probably listed. It is called the loopback adapter address. Only processes on the same computer can use it to connect.

It can be useful for troubleshooting, but you can't use it to connect from another computer. Enable protocolsIn some installations of SQL Server, connecting to the Database Engine from another computer is not enabled unless an administrator uses Configuration Manager to enable it. To enable connections from another computer:. Open SQL Server Configuration Manager, as described earlier. Using Configuration Manager, in the left pane expand SQL Server Network Configuration, and then select the instance of SQL Server that you want to connect to. The right-pane lists the connection protocols available.

Shared Memory is normally enabled. It can only be used from the same computer, so most installations leave Shared Memory enabled. To connect to SQL Server from another computer, you normally use TCP/IP.

If TCP/IP is not enabled, right-click TCP/IP, and then click Enable. If you changed the enabled setting for any protocol, restart the Database Engine. In the left pane select SQL Server Services.

In the right-pane, right-click the instance of the Database Engine, and then click Restart.Testing TCP/IP connectivityConnecting to SQL Server by using TCP/IP requires that Windows can establish the connection. Use the ping tool to test TCP.On the Start menu, click Run. In the Run window type cmd, and then click OK.In the command prompt window, type ping and then the IP address of the computer that is running SQL Server. For example:. IPv4: ping 192.168.1.101.

IPv6: ping fe80::d51d:5ab5:6f09:8f48%11.If your network is properly configured, ping returns Reply from followed by some additional information. If ping returns Destination host unreachable or Request timed out, then TCP/IP is not correctly configured. Errors at this point could indicate a problem with the client computer, the server computer, or something about the network such as a router. To troubleshoot network problems, see.Next, if the ping test succeeded using the IP address, test that the computer name can be resolved to the TCP/IP address. On the client computer, in the command prompt window, type ping and then the computer name of the computer that is running SQL Server. For example, ping newofficepc.If ping to the IP address succeeds, but ping to the computer returns Destination host unreachable or Request timed out you might have old (stale) name resolution information cached on the client computer.

Type ipconfig /flushdns to clear the DNS (Dynamic Name Resolution) cache. Then ping the computer by name again. With the DNS cache empty, the client computer will check for the newest information about the IP address for the server computer.If your network is properly configured, ping returns Reply from followed by some additional information.

If you can successfully ping the server computer by IP address but receive an error such as Destination host unreachable. Or Request timed out. When pinging by computer name, then name resolution is not correctly configured. (For more information, see the 2006 article previously referenced,.) Successful name resolution is not required to connect to SQL Server, but if the computer name cannot be resolved to an IP address, then connections must be made specifying the IP address. Name resolution can be fixed later.Open a port in the firewallBy default, the Windows firewall is turned on and will block connections from another computer. To connect using TCP/IP from another computer, on the SQL Server computer you must configure the firewall to allow connections to the TCP port used by the Database Engine.

The default instance is listening on TCP port 1433, by default. If you have named instances or if you changed the default instance port, the SQL Server TCP port may be listening on another port.

See.If you are connecting to a named instance or a port other than TCP port 1433, you must also open the UDP port 1434 for the SQL Server Browser service. For step by step instruction on opening a port in the Windows firewall, see. Test the connectionOnce you can connect using TCP on the same computer, it's time to try connecting from the client computer. You could theoretically use any client application, but to avoid additional complexity, install the SQL Server Management tools on the client and make the attempt using SQL Server Management Studio.On the client computer, using SQL Server Management Studio, attempt to connect using the IP Address and the TCP port number in the format IP address comma port number. For example, 192.168.1.101,1433.

If this connection fails, then you probably have one of the following problems:. ping of the IP address doesn't work, indicating a general TCP configuration problem.

Go back to the section. SQL Server is not listening on the TCP protocol.

Go back to the section. SQL Server is listening on a port other than the port you specified. Go back to the section. The SQL Server TCP port is being blocked by the firewall. Go back to the section.Once you can connect using the IP address and port number, attempt to connect using the IP address without a port number.

For a default instance, just use the IP address.
