How to configure SQL Server to connect to a remote database

Configuring connection to a remote database in SQL Server primarily involves the following aspects:

1. Ensure that the remote database server allows remote connections: On the remote database server, enable the remote connection feature for SQL Server. This can be configured through SQL Server Configuration Manager by selecting SQL Server Network Configuration -> Protocols -> TCP/IP, enabling the TCP/IP protocol, and configuring the IP address option to allow remote connections.
2. Configure the firewall to allow communication on the SQL Server port: Make sure the firewall allows communication on the SQL Server default port (TCP 1433) or adjust the port number based on the actual situation.
3. Configure connection information in local SQL Server: When connecting to a remote database in SQL Server Management Studio, you will need to enter the correct server name, username, and password. You can choose between Windows Authentication or SQL Server Authentication when connecting, depending on the remote database server’s requirements.
4. Granting remote connection permissions to SQL Server login: On the remote database server, it is necessary to configure the appropriate permissions for the login users connecting to the database. This can be done through SQL Server Management Studio or T-SQL commands to ensure the login users have access to the target database.

In general, connecting to a remote database requires appropriate configuration on both the remote database server and the local SQL Server to ensure smooth network communication and that the login user has permission to access the target database. If there are special network environments or security policies, further configuration and adjustments may be necessary.
