Hello all,

I am attempting to set up a local install of DotNetNuke. I am using 6.1.2 - New Install found here . I have set up a site via IIS that points to the root of the installation. When I navigate there with my browser I see the setup wizard. I get as far as the database connection screen when I run into an issue.

 I have SQL server express 2008 running and set up a empty database for DNN.

 In the server text box I put \SQLEXPRESS and I enter the database name, which is simply "dnn", into the database field. When I  hit next I get the following error:

Connection Error(s):
Index #: 0
Source: .Net SqlClient Data Provider
Class: 20
Number: 87
Message:

 I'm not sure what I am doing wrong. It should be noted that when I want to access my local database server using SQL Server Management Studio I have to specify (local)\SQLEXPRESS as the host. When I try to do this in the DotNetNuke setup I get two errors:

Connection Error(s):
Index #: 0
Source: .Net SqlClient Data Provider
Class: 11
Number: 4060
Message: Invalid Database

Index #: 1
Source: .Net SqlClient Data Provider
Class: 14
Number: 18456
Message: Sql login failed

I have "integrated security" checked as my SQL Server is set up with Windows integrated authentication.

 If anyone has an idea about what I am doing wrong or any suggestions for fixing it I would very much appreciate it. Thanks!

Thanks for the response.

Very strange, the application pool the site is running under should have permissions for that database. I ended up creating a sql user account and connecting to the database using SQL Server authentication.
