I've downloaded the code in chapter 12 and I tried to set it up, but I keep running into a problem. I keep getting a database connection error. I've updated the connection string in the web.config, app.config, and in the setting sections. Are there are there any other locations that I am missing?

Hi,

When u gettin this kind of connection error , please do check the connection address of the database you using.

Here is my connectionstring:
Data Source=machinename;Initial Catalog=HRPaidTimeOff;Integrated Security=True
(I've replaced the name of my computer with machinename)

When I test the connection string in Visual Studio it says it is fine.

I am still getting the following error:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

Any suggestions?

do you have annoymous access turned off and integrated windows authentication turned on in the virtual directory?
