Go to Control Panel > Windows Firewall > Change Settings > Exceptions > Add Port If SQL Server has named instance (another instance besides default instance) is installed, SQL Server browser should also be added to the exception, as described in Step 7. As described, by default SQL Server runs on port 1433, but if default port is changed then the new port should be added to exception. All the ports on which SQL Server is running should be added to exception and firewall should filter all the traffic from those ports. Time and again, SQL Server ports are not open in firewall as well. By default, many of the ports and services are refrained from running by firewall. Windows Firewall is very efficacious in protecting the Operating system from all sorts of malicious attacks. Right click and go to menu properties to select location where default port of SQL Server can be changed. You must restart SQL Server Services for all the changes to take effect.
Go to All Programs > Microsoft SQL Server 2008 > Configuration Tools > SQL Server Configuration Manager > Select TCP/IP TCP/IP should be enabled for SQL Server to be connected. This port can be changed through SQL Server Configuration Manager. The default port of SQL Server installation is 1433. When two or more SQL Servers are connected across network they do all communication using TCP/IP. If SQL Server is not installed as default instance SQL Server Browser should be running together with it we will explore this further in Topic 5.Ģ) Enable TCP/IP in SQL Server Configuration I have confronted numerous situations when these nerve-wracking errors crop up, and most of the time when I try to troubleshoot I notice that SQL Server services are neither running nor installed.

Run “ sqlcmd -L” in your command prompt to ascertain if your server is included in your network list. In addition, ensure that your remote server is in the same network. 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”.
