Is Your SQL Server Configured to Allow Remote Connections?

Hello Dev, if you are planning to use SQL Server remotely, it is important to check if it is configured to allow remote connections. If not, you won’t be able to connect to your SQL Server from a remote computer. In this article, we will guide you on how to check and configure your SQL Server to allow remote connections.

What is Remote Connection in SQL Server?

In SQL Server, remote connections refer to connections made to a SQL Server instance from a computer that is not in the same network as the SQL Server. By default, SQL Server is configured to disallow remote connections for security reasons. This means you won’t be able to connect to your SQL Server from a remote location unless it is configured to allow remote connections.

How to Check if SQL Server is Configured to Allow Remote Connections

Before we dive into configuring SQL Server to allow remote connections, let’s check if it is already configured to allow remote connections. Here are the steps to check:

If the “Allow remote connections to this server” option is not checked, you need to configure your SQL Server to allow remote connections. Let’s move on to the next section to learn how to configure SQL Server to allow remote connections.

How to Configure SQL Server to Allow Remote Connections

Configuring SQL Server to allow remote connections involves a few steps. Here is a step-by-step guide:

Step 1: Enable TCP/IP Protocol

Step 2: Configure Firewall Settings

If you have a firewall enabled on the SQL Server computer, you need to configure it to allow incoming connections on SQL Server TCP port (default port is 1433). Here are the steps to allow incoming connections on SQL Server TCP port:

Step 3: Enable SQL Server Authentication Mode

By default, SQL Server is configured to use Windows Authentication mode, which means you can only connect to SQL Server with a Windows user account. If you want to connect to SQL Server with a SQL Server user account, you need to enable SQL Server Authentication mode. Here are the steps to enable SQL Server Authentication mode:
