To create a valid connection string using TCP/IP, you must: Specify an Alias Name. For the Server, enter either a server name to which you can connect using the PING utility, or an IP address to which you can connect using the PING utility. For a named instance append the instance name. Specify TCP/IP for the Protocol Use the TCP/IP Properties (IP Addresses Tab) dialog box to configure the TCP/IP protocol options for a specific IP address. Only TCP Dynamic Ports and TCP Port can be configured for all addresses at once by selecting IP All. Changes take effect when SQL Server SQL Server is restarted Wenn die Eigenschaft Auf Alle lauschen unter TCP/IP-Eigenschaften (Registerkarte Protokoll) auf Nein festgelegt ist, gibt diese Eigenschaft an, ob SQL Server auf die IP-Adresse lauscht. If the Listen All property on the TCP/IP Properties (Protocol Tab) is set to No, this property indicates whether SQL Server is listening on the IP address

Right-click on TCP/IP Protocol Name and select the Property option
By default, the SQL Server instance listens on TCP port 1433, where the named instances located in the same server will be configured for dynamic TCP ports, selecting an available TCP port each time the SQL Server service restarted. SQL Server Bowser Service helps the client identifying that used TCP port when he tries to connect. It is better to configure the SQL Server named instance to. The TCP/IP Protocol must be enabled in the SQL Server Configuration Manager for both the named instance and the client protocols. Restart the service after changing.

Enable TCP/IP Connection for SQL Server The client must connect to the instance of SQL Server 2005 using the TCP/IP protocol. For example, you can put the TCP/IP protocol at the top of the client's protocol order. Or you can add the prefix tcp: in the connection string to specify that the connection will use the TCP/IP protocol. For SQL Server 2008 and onward, this requirement is relaxed because both Named Pipes and Shared memory.
Because of this, the TCP/IP protocol needs to be enabled on the MS SQL Server database in order for either driver to make a connection. Both the MS SQL Server and jTDS JDBC drivers can be downloaded from their respective web sites. Once the driver jar file is downloaded and included the the classpath of the Java program, a connection can be. 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. 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, se In this article, we will show you how to check the current TCP port on which a named or default MS SQL Server instance is listening (waiting for connection on), how to change an SQL Server connection port to a static/dynamic one, and how the SQL Server Browser service is used by clients to connect to MSSQL Now when all rules are set up, you are ready to connect to remote SQL Server.
