Trying to get the RC of DNN7 to work (installed a test instance at http://dnn7.thehway.com). I installed SQL Server 2012 Express to run the instance, but I can't seem to connect to it. Here's the error:

ERROR:Index #: 0
Source: .Net SqlClient Data Provider
Class: 14
Number: 15350

Running IIS 7 on Windows Server 2008 R2. I did try editing the web.config file to reference a new database I created but no joy. I'm sure it's some sort of configuration issue, but I can't seem to find it.

Thanks, Sebastian. Actually, I figured-out the problem; by default, the web.config file assumes that DNN7 is being installed on a local machine, while I was trying to install it on a remote server. Hence, I had to change the connection string from

<add name="SiteSqlServer" connectionString="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|database.mdf;" providerName="System.Data.SqlClient" />

to

<add name="SiteSqlServer" connectionString="Data Source=.\SQLExpress;Initial Catalog=database;Integrated Security=True" providerName="System.Data.SqlClient" />

Hence, I not only had to remove the AttachDBFilename reference but the UserInstance parameter as well. Once I made these changes, DNN7 immediately found my database and installed--it's all working at http://dnn7.thehway.com. Wonderful!
