A number of my books rely on database access and one of the most common servers that I’ve used in the past is SQL Server. In order to access any server, the server must be running. It only makes sense that you can’t access something that isn’t listening. The problem is that SQL Server may not start automatically for a number of reasons on your system and that Visual Studio doesn’t always make it apparent that the server isn’t running. You may get a nebulous message when you try to make a connection that doesn’t tell you anything. (No, SQL Server doesn’t start automatically when you make a request for data.) With this in mind, a post of checking the status of SQL Server is important.
Normally, I would tell you to use the tools that come with SQL Server to check the status of the server. However, some versions of SQL Server Express Edition install without the standard tools now, such as SQL Server Management Studio. Without access to these tools, it may seem as if checking the server status is impossible. Fortunately, you have other options.
The best way to check the status of SQL Server on your system is to use the Services console found in the Administrative Tools folder of the Control Panel. The Services console is one of a number of Microsoft Management Console (MMC) snap-ins that Windows installs automatically for you. However, to use this console, you must have administrator rights on the target system. Without these rights, you truly are out of luck in checking the status of your SQL Server setup and will need to get an administrator to help you.
Open the Services console and you find a list of all of the services installed on your system. Scroll down the list and you should find one or more SQL Server entries like the ones shown here.
In order to work successfully with the examples in my book, you should have SQL Server set to start automatically. In addition, when you check the service, you should see Started in the Status column as shown in the screenshot. If you don’t see Started, then highlight the service as shown and click the Start link you see on the left side (not shown in this case because the service is already started).
To make the examples easier to work with, you should also ensure that the SQL Server Browser service is started. This service makes it possible for Visual Studio to find the SQL Server installation on your system. Without this service, you must correctly type the name of the SQL Server installation you want to use when creating a connection, which is both time consuming and error prone.
If you find that you encounter problems making database examples in my books work, please check the status of SQL Server to ensure the service is actually started.

I may not be able to fix every problem you encounter, but I often have a good idea of what problems you might be seeing on your system and will do my best to help you.
