In this tip, we look at what may be causes to these errors and how to resolve. Solution There could be several reasons you get these error messages. Follow the below steps to see if you can resolve the issue. Step 1Make sure you are able to ping the physical server where SQL Server is installed from the client machine. If not, you can try to connect to the SQL Server using an IP Address (for default instance) or IP Address\Instance Name for a named instance. If it resolves using an IP address, you can add the SQL Server machine into /etc/host file. To add the entry in the /host file type %SystemRoot%\system32\drivers\etc\ in the run window and open the host file using Notepad. In the below image I added IP address 74.200.243.253 with a machine name of SQLDBPool. Now I should be able to use the machine name instead of the IP address to connect to the SQL Server. Step 2 Make sure the SQL services are running You can check the SQL Server services by using the SC command or SQL Server Configuration Manager. Many times you may find that the SQL Server instance is not running. Usin
