ThomasG:
Το web config που έχω είναι:

<connectionStrings>
        <remove name="LocalSqlServer"/>
        
        <add name="LocalSqlServer" connectionString="Data Source=ΧΧ.Χ.Χ.ΧΧΧ,1433;Network Library=DBMSSOCN;Initial Catalog=acheloos;User ID=username;Password=password;" providerName="System.Data.SqlClient"/>
    </connectionStrings>

Μπορεί το πρόβλημα σου να είναι ότι η Port του Remote SQL Server είναι διαφορετική από 1433. (Είναι στο 99% των περιπτώσεων) Το τσέκαρες?
