Sql Server Error 10061
We have an application that uses MSDE as its ‘Back-end’. It has been working fine for years. We connection failed sql server error 11001 have however had to recently re-build the Operating System onour ownServer that it was running on. Original O/S Environment We used Windows Server 2008 r2, using Hyper-V to run Windows sql server error 53 Server 2003 so that we can use MSDE to run our application. We do not want to change to later versions of SQL Server Express as they no-longer support Replication. NEW O/S Environment When we re-built the Server we went for Windows Server 2008 r2, using Hyper-V to run Windows 7 Enterprise so that we can use MSDE to run

our application. We have used this setup many times before and know that MSDE runs quite happily under Windows 7. Servers have been renamed The real Windows Server 2008 r2 machine used to be called FILESERVER. It is now called FILE-SERVER. The virtual machine running our application was originally called GEMSERVER. It is now called GEM-SERVER. What’s happening on the Server The application is running fine. We can access the underlying MDSE Database with SQL Server 2005 Management Studio Express without problem. We can build a test ODBC Data Source and connect to the ‘SQL Server’ Database, again without problems. What’s happening onthe Client PC The application does not connect.

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. Using SQL Server Configuration Manager Using SC command Please note for a named instance you have to write the command as
