Post-Installation Configuration

Configuring firewall settings

After installing SQL Server, you need to configure your firewall settings to allow remote connections to the SQL Server database engine. This can be done by adding a rule to your firewall that allows TCP port 1433 (the default port for SQL Server).

Enabling protocols for remote connections

By default, SQL Server is only configured to allow remote connections using the TCP/IP protocol. If you want to allow remote connections using other protocols, such as Named Pipes or Shared Memory, you must enable these protocols in the SQL Server Network Configuration tool.

Configuring memory settings and other performance tweaks

The amount of memory that SQL Server uses can significantly impact performance. You can configure the memory settings for SQL Server by editing the sqlservr.ini file. You can also use the sp_configure stored procedure to configure the memory settings dynamically.

Setting up server-level security (logins, roles, permissions)

Server-level security is important for protecting your SQL Server database from unauthorized access. You can set up server-level security by creating logins, roles, and permissions. Logins identify users who can connect to SQL Server. Roles are groups of users who have similar permissions. Permissions determine what actions users can perform on the database.

Configuring database options and maintenance plans

There are several database options that you can configure to improve the performance and maintainability of your SQL Server database. You can also create maintenance plans to automate tasks such as backing up the database and optimizing the database.

Connecting to SQL Server Express

  2. Expand the SQL Server Network Configuration node.
  3. Expand the Protocols for “” node.
  4. Right-click on the TCP/IP protocol and select Enable.
  5. In the TCP/IP Properties dialog box, specify the port number and IP address from which you want to allow connections.
  6. Click on the OK button.

Connecting programmatically using connection strings

A connection string is a text string that contains the information that SQL Server needs to connect to a database. You can use connection strings to connect to SQL Server programmatically.

The following is an example of a connection string for SQL Server Express:

Data Source=localhost; Initial Catalog=master; Integrated Security=True

The Data Source property specifies the name of the server hosting SQL Server Express. The Initial Catalog property specifies the database name you want to connect to. The Integrated Security property specifies the authentication method that you want to use.

To connect to SQL Server programmatically, you can use the System.Data.SqlClient namespace. The following code shows how to connect to SQL Server using a connection string:

using System.Data.SqlClient;
public class Program
public static void Main()
string connectionString = “Data Source=localhost;Initial Catalog=master;Integrated Security=True”; SqlConnection connection = new SqlConnection(connectionString); connection.Open();

This code will connect to SQL Server Express on the local computer and open a connection to the master database.
