I'm trying to follow [this](http://support.microsoft.com/kb/307283) example but I get an Exception related to the connection string telling me that the server was not found or was not accessible. The tutorial itself tells me on step 5 to "Change the connection string to point to your computer running SQL Server". I don't know if my SQL Server is running or not and if it is I don't know what would be the name of the server. I know I installed SQL Server when I installed VS 2010 (I did a full installation), so it should be somewhere. I haven't changed anything in the SQL Server configuration so everything should be on what is default.
