DB Connection Issue

Hi Experts!

Thanks for reading this.

Have a Win console that reads a table on SQL Sever.

Ran it locally and it works.

Ran it on the DEV server (Win 2008) and we have this error:

 ExecuteReader requires an open and available Connection. The connection's current state is closed.

On the DEV server there's an ODBC instance (SomeDB)

Here's the connectionstring for console app:

<add key="SQLConnection" value="Data Source=SeverA\DB1;Initial Catalog=SomeDB;Integrated Security=SSPI" />

*SomeDB = a db name that the table resides

Any ideas what's causing the issue?
