Understanding Remote Connections to SQL Server

Before we start, let’s understand what remote connections to SQL Server mean. Remote connections refer to connecting to SQL Server from a different computer than the one where SQL Server is installed. These connections enable users to access SQL Server data from a remote location, making it ideal for remote workers, client-server applications, or web applications.

By default, remote connections are disabled in SQL Server. Therefore, you need to configure SQL Server to allow remote connections. The process of enabling remote connections varies depending on the version of SQL Server that you are using. Let’s dive into each step in detail.
