Am having problems connecting to named SQL 2005 instance (named SQL1) running on XP Pro. Here is the connect strings I am using. This is DNN Version 4.02, compiled from Source. Any thoughts would be appreciated.

ConnectionString="Data Source=TOSHIBA-USER\SQL1;Initial Catalog=DotNetNuke;uid=DNN;pwd=DNN;"

<add key="SiteSqlServer" value="Data Source=TOSHIBA-USER\SQL1;Initial Catalog=DotNetNuke;uid=DNN;pwd=DNN;"/>

I have also tried     

connectionString="Server=TOSHIBA-USER\SQL1;Database=DotNetNuke;uid=DNN;pwd=DNN;"

Database is new and empty, and I am pretty sure that the user authentication and permissions are OK.

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace fproblor more information about the error and where it originated in the code.

It's

<add key="SiteSqlServer" value="server=MachineName\InstanceName;Database=DotNetNuke;uid=DNN;pwd=DNN;" />

Is your machine name TOSHIBA-USER?

Hope this helps.

Hey Barnett,
There's actually a couple things that potentially could be the problem.  First, what version of SQL Server are you running?  With Express, by default, it doesn't actually listen for remote connections so it would not be possible, unless you changed the default settings, to run the site and the database on different servers.  Also, with DNN 4, there's actually two places that the connection string is stored in the web.config, so make sure you change both of them!

Always glad to help!

Oh Dummy me!

When you first start working with something complex you tend to look for the hard answers rather than the easy ones. And, in interest of keeping the post short I left out part of the Web.config. Seems I had removed the closing right arrow from the comment header causing the entire connection string to be commented out. I was editing in a text editor and it was not color coded. when I opened it in VS it was immediately obvious!

NO PROBLEM CONNECTING WITH A NAMED SQL 2005 INSTANCE.
