***First***, make sure your database engine is configured to accept remote connections:
- Start > All Programs > SQL Server 2005 > Configuration Tools > SQL Server Surface Area Configuration
- Click on Surface Area Configuration for Services and Connections
- Select the instance that is having a problem > Database Engine > Remote Connections
- Enable local and remote connections
- Restart instance
***Second***, You may need to create an exception on the firewall for the SQL Server instance and port you are using
- Start > Run > Firewall.cpl
- Click on exceptions tab
- Add the sqlservr.exe (typically located in C:\Program Files (x86)\Microsoft SQL Server\MSSQL.x\MSSQL\Binn, check your installs for the actual folder path), and port (default is 1433)
- Check your connection string as well
***Third***, check if your SQL server services is up and running properly
Go to All Programs >> Microsoft SQL Server 2008 >> Configuration Tools >> SQL Server Configuration Manager >> SQL Server Services, and check if SQL Server service status is “Running”.
In addition, ensure that your remote server is in the same network. Run “sqlcmd -L” in your command prompt to ascertain if your server is included in your network list. You can even find tutorial for the same here SQL SERVER – Find All Servers From Local Network – Using sqlcmd – Detect Installed SQL Server on Network.
***Next***, Enable TCP/IP in SQL Server Configuration
Go to All Programs >> Microsoft SQL Server 2008 >> Configuration Tools >> SQL Server Configuration Manager >> Select TCP/IP. Right click and select enable
***Last***, Go to your firewall setting, under exception tab, select add port include TCP:1433 and tick the SQL check box.
